Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42510, here are decompositions:

11 + 42499 = 42510
19 + 42491 = 42510
23 + 42487 = 42510
37 + 42473 = 42510
43 + 42467 = 42510
47 + 42463 = 42510
53 + 42457 = 42510
59 + 42451 = 42510

Showing the first eight; more decompositions exist.
