Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715688, here are decompositions:

17 + 8715671 = 8715688
29 + 8715659 = 8715688
41 + 8715647 = 8715688
71 + 8715617 = 8715688
101 + 8715587 = 8715688
239 + 8715449 = 8715688
257 + 8715431 = 8715688
419 + 8715269 = 8715688

Showing the first eight; more decompositions exist.
