Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661518, here are decompositions:

31 + 8661487 = 8661518
79 + 8661439 = 8661518
277 + 8661241 = 8661518
337 + 8661181 = 8661518
457 + 8661061 = 8661518
571 + 8660947 = 8661518
631 + 8660887 = 8661518
751 + 8660767 = 8661518

Showing the first eight; more decompositions exist.
