Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677818, here are decompositions:

47 + 8677771 = 8677818
59 + 8677759 = 8677818
137 + 8677681 = 8677818
167 + 8677651 = 8677818
211 + 8677607 = 8677818
241 + 8677577 = 8677818
307 + 8677511 = 8677818
337 + 8677481 = 8677818

Showing the first eight; more decompositions exist.
