Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647988, here are decompositions:

61 + 8647927 = 8647988
109 + 8647879 = 8647988
229 + 8647759 = 8647988
277 + 8647711 = 8647988
331 + 8647657 = 8647988
409 + 8647579 = 8647988
421 + 8647567 = 8647988
457 + 8647531 = 8647988

Showing the first eight; more decompositions exist.
