Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640510, here are decompositions:

7 + 8640503 = 8640510
17 + 8640493 = 8640510
29 + 8640481 = 8640510
59 + 8640451 = 8640510
71 + 8640439 = 8640510
83 + 8640427 = 8640510
101 + 8640409 = 8640510
103 + 8640407 = 8640510

Showing the first eight; more decompositions exist.
