Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12520, here are decompositions:

3 + 12517 = 12520
17 + 12503 = 12520
23 + 12497 = 12520
29 + 12491 = 12520
41 + 12479 = 12520
47 + 12473 = 12520
83 + 12437 = 12520
107 + 12413 = 12520

Showing the first eight; more decompositions exist.
