Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637422, here are decompositions:

43 + 8637379 = 8637422
103 + 8637319 = 8637422
271 + 8637151 = 8637422
331 + 8637091 = 8637422
433 + 8636989 = 8637422
463 + 8636959 = 8637422
499 + 8636923 = 8637422
523 + 8636899 = 8637422

Showing the first eight; more decompositions exist.
