Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731656, here are decompositions:

13 + 8731643 = 8731656
19 + 8731637 = 8731656
29 + 8731627 = 8731656
47 + 8731609 = 8731656
127 + 8731529 = 8731656
163 + 8731493 = 8731656
179 + 8731477 = 8731656
223 + 8731433 = 8731656

Showing the first eight; more decompositions exist.
