Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105656, here are decompositions:

3 + 105653 = 105656
7 + 105649 = 105656
37 + 105619 = 105656
43 + 105613 = 105656
127 + 105529 = 105656
139 + 105517 = 105656
157 + 105499 = 105656
277 + 105379 = 105656

Showing the first eight; more decompositions exist.
