Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672768, here are decompositions:

37 + 8672731 = 8672768
61 + 8672707 = 8672768
109 + 8672659 = 8672768
127 + 8672641 = 8672768
229 + 8672539 = 8672768
241 + 8672527 = 8672768
421 + 8672347 = 8672768
607 + 8672161 = 8672768

Showing the first eight; more decompositions exist.
