Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12712, here are decompositions:

23 + 12689 = 12712
41 + 12671 = 12712
53 + 12659 = 12712
59 + 12653 = 12712
71 + 12641 = 12712
101 + 12611 = 12712
173 + 12539 = 12712
233 + 12479 = 12712

Showing the first eight; more decompositions exist.
