Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625666, here are decompositions:

17 + 8625649 = 8625666
29 + 8625637 = 8625666
67 + 8625599 = 8625666
79 + 8625587 = 8625666
107 + 8625559 = 8625666
113 + 8625553 = 8625666
139 + 8625527 = 8625666
149 + 8625517 = 8625666

Showing the first eight; more decompositions exist.
