Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672772, here are decompositions:

5 + 8672767 = 8672772
41 + 8672731 = 8672772
113 + 8672659 = 8672772
131 + 8672641 = 8672772
151 + 8672621 = 8672772
211 + 8672561 = 8672772
233 + 8672539 = 8672772
263 + 8672509 = 8672772

Showing the first eight; more decompositions exist.
