Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672512, here are decompositions:

3 + 8672509 = 8672512
11 + 8672501 = 8672512
29 + 8672483 = 8672512
41 + 8672471 = 8672512
71 + 8672441 = 8672512
83 + 8672429 = 8672512
89 + 8672423 = 8672512
131 + 8672381 = 8672512

Showing the first eight; more decompositions exist.
