Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637654, here are decompositions:

13 + 8637641 = 8637654
17 + 8637637 = 8637654
37 + 8637617 = 8637654
43 + 8637611 = 8637654
127 + 8637527 = 8637654
131 + 8637523 = 8637654
163 + 8637491 = 8637654
173 + 8637481 = 8637654

Showing the first eight; more decompositions exist.
