Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12530, here are decompositions:

3 + 12527 = 12530
13 + 12517 = 12530
19 + 12511 = 12530
43 + 12487 = 12530
73 + 12457 = 12530
79 + 12451 = 12530
97 + 12433 = 12530
109 + 12421 = 12530

Showing the first eight; more decompositions exist.
