Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638108, here are decompositions:

41 + 8638067 = 8638108
47 + 8638061 = 8638108
179 + 8637929 = 8638108
239 + 8637869 = 8638108
317 + 8637791 = 8638108
359 + 8637749 = 8638108
467 + 8637641 = 8638108
491 + 8637617 = 8638108

Showing the first eight; more decompositions exist.
