Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629680, here are decompositions:

19 + 8629661 = 8629680
29 + 8629651 = 8629680
43 + 8629637 = 8629680
67 + 8629613 = 8629680
83 + 8629597 = 8629680
97 + 8629583 = 8629680
173 + 8629507 = 8629680
197 + 8629483 = 8629680

Showing the first eight; more decompositions exist.
