Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674840, here are decompositions:

47 + 8674793 = 8674840
59 + 8674781 = 8674840
71 + 8674769 = 8674840
113 + 8674727 = 8674840
173 + 8674667 = 8674840
263 + 8674577 = 8674840
269 + 8674571 = 8674840
431 + 8674409 = 8674840

Showing the first eight; more decompositions exist.
