Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672678, here are decompositions:

19 + 8672659 = 8672678
31 + 8672647 = 8672678
37 + 8672641 = 8672678
127 + 8672551 = 8672678
139 + 8672539 = 8672678
151 + 8672527 = 8672678
271 + 8672407 = 8672678
331 + 8672347 = 8672678

Showing the first eight; more decompositions exist.
