Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672738, here are decompositions:

7 + 8672731 = 8672738
31 + 8672707 = 8672738
79 + 8672659 = 8672738
97 + 8672641 = 8672738
199 + 8672539 = 8672738
211 + 8672527 = 8672738
229 + 8672509 = 8672738
331 + 8672407 = 8672738

Showing the first eight; more decompositions exist.
