Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12492, here are decompositions:

5 + 12487 = 12492
13 + 12479 = 12492
19 + 12473 = 12492
41 + 12451 = 12492
59 + 12433 = 12492
71 + 12421 = 12492
79 + 12413 = 12492
83 + 12409 = 12492

Showing the first eight; more decompositions exist.
