Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625660, here are decompositions:

11 + 8625649 = 8625660
19 + 8625641 = 8625660
23 + 8625637 = 8625660
61 + 8625599 = 8625660
73 + 8625587 = 8625660
101 + 8625559 = 8625660
107 + 8625553 = 8625660
139 + 8625521 = 8625660

Showing the first eight; more decompositions exist.
