Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673656, here are decompositions:

109 + 8673547 = 8673656
139 + 8673517 = 8673656
157 + 8673499 = 8673656
193 + 8673463 = 8673656
223 + 8673433 = 8673656
283 + 8673373 = 8673656
457 + 8673199 = 8673656
499 + 8673157 = 8673656

Showing the first eight; more decompositions exist.
