Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637688, here are decompositions:

47 + 8637641 = 8637688
71 + 8637617 = 8637688
167 + 8637521 = 8637688
179 + 8637509 = 8637688
197 + 8637491 = 8637688
239 + 8637449 = 8637688
347 + 8637341 = 8637688
431 + 8637257 = 8637688

Showing the first eight; more decompositions exist.
