Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747918, here are decompositions:

61 + 8747857 = 8747918
181 + 8747737 = 8747918
229 + 8747689 = 8747918
241 + 8747677 = 8747918
379 + 8747539 = 8747918
499 + 8747419 = 8747918
661 + 8747257 = 8747918
727 + 8747191 = 8747918

Showing the first eight; more decompositions exist.
