Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657776, here are decompositions:

5 + 8657771 = 8657776
53 + 8657723 = 8657776
89 + 8657687 = 8657776
137 + 8657639 = 8657776
263 + 8657513 = 8657776
353 + 8657423 = 8657776
389 + 8657387 = 8657776
419 + 8657357 = 8657776

Showing the first eight; more decompositions exist.
