Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672628, here are decompositions:

7 + 8672621 = 8672628
31 + 8672597 = 8672628
67 + 8672561 = 8672628
89 + 8672539 = 8672628
101 + 8672527 = 8672628
109 + 8672519 = 8672628
127 + 8672501 = 8672628
157 + 8672471 = 8672628

Showing the first eight; more decompositions exist.
