Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642810, here are decompositions:

37 + 8642773 = 8642810
229 + 8642581 = 8642810
277 + 8642533 = 8642810
613 + 8642197 = 8642810
691 + 8642119 = 8642810
733 + 8642077 = 8642810
751 + 8642059 = 8642810
823 + 8641987 = 8642810

Showing the first eight; more decompositions exist.
