Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126510, here are decompositions:

11 + 126499 = 126510
17 + 126493 = 126510
19 + 126491 = 126510
23 + 126487 = 126510
29 + 126481 = 126510
37 + 126473 = 126510
53 + 126457 = 126510
67 + 126443 = 126510

Showing the first eight; more decompositions exist.
