Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12510, here are decompositions:

7 + 12503 = 12510
13 + 12497 = 12510
19 + 12491 = 12510
23 + 12487 = 12510
31 + 12479 = 12510
37 + 12473 = 12510
53 + 12457 = 12510
59 + 12451 = 12510

Showing the first eight; more decompositions exist.
