Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672518, here are decompositions:

5 + 8672513 = 8672518
17 + 8672501 = 8672518
47 + 8672471 = 8672518
89 + 8672429 = 8672518
131 + 8672387 = 8672518
137 + 8672381 = 8672518
251 + 8672267 = 8672518
311 + 8672207 = 8672518

Showing the first eight; more decompositions exist.
