Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12512, here are decompositions:

61 + 12451 = 12512
79 + 12433 = 12512
103 + 12409 = 12512
139 + 12373 = 12512
211 + 12301 = 12512
223 + 12289 = 12512
271 + 12241 = 12512
349 + 12163 = 12512

Showing the first eight; more decompositions exist.
