Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617964, here are decompositions:

31 + 8617933 = 8617964
37 + 8617927 = 8617964
127 + 8617837 = 8617964
211 + 8617753 = 8617964
283 + 8617681 = 8617964
337 + 8617627 = 8617964
547 + 8617417 = 8617964
631 + 8617333 = 8617964

Showing the first eight; more decompositions exist.
