Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672776, here are decompositions:

3 + 8672773 = 8672776
53 + 8672723 = 8672776
89 + 8672687 = 8672776
137 + 8672639 = 8672776
179 + 8672597 = 8672776
257 + 8672519 = 8672776
263 + 8672513 = 8672776
293 + 8672483 = 8672776

Showing the first eight; more decompositions exist.
