Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657522, here are decompositions:

19 + 8657503 = 8657522
61 + 8657461 = 8657522
73 + 8657449 = 8657522
199 + 8657323 = 8657522
283 + 8657239 = 8657522
619 + 8656903 = 8657522
631 + 8656891 = 8657522
673 + 8656849 = 8657522

Showing the first eight; more decompositions exist.
