Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657422, here are decompositions:

41 + 8657381 = 8657422
89 + 8657333 = 8657422
113 + 8657309 = 8657422
131 + 8657291 = 8657422
173 + 8657249 = 8657422
311 + 8657111 = 8657422
353 + 8657069 = 8657422
401 + 8657021 = 8657422

Showing the first eight; more decompositions exist.
