Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672680, here are decompositions:

41 + 8672639 = 8672680
59 + 8672621 = 8672680
83 + 8672597 = 8672680
167 + 8672513 = 8672680
179 + 8672501 = 8672680
197 + 8672483 = 8672680
239 + 8672441 = 8672680
251 + 8672429 = 8672680

Showing the first eight; more decompositions exist.
