Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672810, here are decompositions:

19 + 8672791 = 8672810
31 + 8672779 = 8672810
37 + 8672773 = 8672810
43 + 8672767 = 8672810
79 + 8672731 = 8672810
103 + 8672707 = 8672810
151 + 8672659 = 8672810
163 + 8672647 = 8672810

Showing the first eight; more decompositions exist.
