Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12506, here are decompositions:

3 + 12503 = 12506
19 + 12487 = 12506
73 + 12433 = 12506
97 + 12409 = 12506
127 + 12379 = 12506
163 + 12343 = 12506
229 + 12277 = 12506
349 + 12157 = 12506

Showing the first eight; more decompositions exist.
