Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672686, here are decompositions:

47 + 8672639 = 8672686
89 + 8672597 = 8672686
167 + 8672519 = 8672686
173 + 8672513 = 8672686
257 + 8672429 = 8672686
263 + 8672423 = 8672686
353 + 8672333 = 8672686
389 + 8672297 = 8672686

Showing the first eight; more decompositions exist.
