Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70518, here are decompositions:

11 + 70507 = 70518
17 + 70501 = 70518
29 + 70489 = 70518
31 + 70487 = 70518
37 + 70481 = 70518
59 + 70459 = 70518
61 + 70457 = 70518
67 + 70451 = 70518

Showing the first eight; more decompositions exist.
