Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672816, here are decompositions:

37 + 8672779 = 8672816
43 + 8672773 = 8672816
109 + 8672707 = 8672816
157 + 8672659 = 8672816
277 + 8672539 = 8672816
307 + 8672509 = 8672816
409 + 8672407 = 8672816
463 + 8672353 = 8672816

Showing the first eight; more decompositions exist.
