Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642566, here are decompositions:

47 + 8642519 = 8642566
59 + 8642507 = 8642566
113 + 8642453 = 8642566
137 + 8642429 = 8642566
263 + 8642303 = 8642566
419 + 8642147 = 8642566
467 + 8642099 = 8642566
503 + 8642063 = 8642566

Showing the first eight; more decompositions exist.
