Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12516, here are decompositions:

5 + 12511 = 12516
13 + 12503 = 12516
19 + 12497 = 12516
29 + 12487 = 12516
37 + 12479 = 12516
43 + 12473 = 12516
59 + 12457 = 12516
79 + 12437 = 12516

Showing the first eight; more decompositions exist.
