Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637916, here are decompositions:

47 + 8637869 = 8637916
137 + 8637779 = 8637916
167 + 8637749 = 8637916
389 + 8637527 = 8637916
449 + 8637467 = 8637916
467 + 8637449 = 8637916
593 + 8637323 = 8637916
653 + 8637263 = 8637916

Showing the first eight; more decompositions exist.
