I did some research on the disassembly of prime numbers for months and Made my own assumptions - KYT's conjecture.

More explanation about KYT's conjecture is described as follows:

a is a positive integer and is even, a>=8, b=a+18, a=c+D, c, D,E are prime numbers.

a=c+D

b=c+E

E=D+18=b-c

The even numbers a and b are split into two prime numbers. There must be a prime number c.

More examples are as follows:

10=3+7;5+5

28=5+23;11+17

46=3+43;5+41;17+29;23+23

64=3+61;5+59;11+53 ;17+47;23+41

82=3+79;11+71 ;23+59;29+53;41+41

.......

.......

10000= 4517+5483

10018= 4517+5501

10036= 4517+5519

Larger even number, it is difficult to break down into 2 prime numbers.

Is there an example where the number c does not exist?
