Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672560, here are decompositions:

41 + 8672519 = 8672560
47 + 8672513 = 8672560
59 + 8672501 = 8672560
89 + 8672471 = 8672560
131 + 8672429 = 8672560
137 + 8672423 = 8672560
173 + 8672387 = 8672560
179 + 8672381 = 8672560

Showing the first eight; more decompositions exist.
