Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12650, here are decompositions:

3 + 12647 = 12650
13 + 12637 = 12650
31 + 12619 = 12650
37 + 12613 = 12650
61 + 12589 = 12650
67 + 12583 = 12650
73 + 12577 = 12650
97 + 12553 = 12650

Showing the first eight; more decompositions exist.
