Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12518, here are decompositions:

7 + 12511 = 12518
31 + 12487 = 12518
61 + 12457 = 12518
67 + 12451 = 12518
97 + 12421 = 12518
109 + 12409 = 12518
127 + 12391 = 12518
139 + 12379 = 12518

Showing the first eight; more decompositions exist.
