Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672746, here are decompositions:

23 + 8672723 = 8672746
59 + 8672687 = 8672746
107 + 8672639 = 8672746
149 + 8672597 = 8672746
227 + 8672519 = 8672746
233 + 8672513 = 8672746
263 + 8672483 = 8672746
317 + 8672429 = 8672746

Showing the first eight; more decompositions exist.
