Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718770, here are decompositions:

13 + 8718757 = 8718770
37 + 8718733 = 8718770
43 + 8718727 = 8718770
61 + 8718709 = 8718770
97 + 8718673 = 8718770
199 + 8718571 = 8718770
283 + 8718487 = 8718770
331 + 8718439 = 8718770

Showing the first eight; more decompositions exist.
