Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672722, here are decompositions:

83 + 8672639 = 8672722
101 + 8672621 = 8672722
239 + 8672483 = 8672722
251 + 8672471 = 8672722
281 + 8672441 = 8672722
293 + 8672429 = 8672722
389 + 8672333 = 8672722
449 + 8672273 = 8672722

Showing the first eight; more decompositions exist.
