Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736688, here are decompositions:

5 + 8736683 = 8736688
29 + 8736659 = 8736688
41 + 8736647 = 8736688
71 + 8736617 = 8736688
179 + 8736509 = 8736688
227 + 8736461 = 8736688
239 + 8736449 = 8736688
347 + 8736341 = 8736688

Showing the first eight; more decompositions exist.
