Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629720, here are decompositions:

41 + 8629679 = 8629720
59 + 8629661 = 8629720
83 + 8629637 = 8629720
107 + 8629613 = 8629720
137 + 8629583 = 8629720
311 + 8629409 = 8629720
479 + 8629241 = 8629720
521 + 8629199 = 8629720

Showing the first eight; more decompositions exist.
