Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717156, here are decompositions:

37 + 8717119 = 8717156
43 + 8717113 = 8717156
157 + 8716999 = 8717156
199 + 8716957 = 8717156
313 + 8716843 = 8717156
337 + 8716819 = 8717156
373 + 8716783 = 8717156
397 + 8716759 = 8717156

Showing the first eight; more decompositions exist.
