Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672688, here are decompositions:

29 + 8672659 = 8672688
41 + 8672647 = 8672688
47 + 8672641 = 8672688
67 + 8672621 = 8672688
127 + 8672561 = 8672688
137 + 8672551 = 8672688
149 + 8672539 = 8672688
179 + 8672509 = 8672688

Showing the first eight; more decompositions exist.
