Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123712, here are decompositions:

5 + 123707 = 123712
11 + 123701 = 123712
59 + 123653 = 123712
131 + 123581 = 123712
233 + 123479 = 123712
263 + 123449 = 123712
293 + 123419 = 123712
311 + 123401 = 123712

Showing the first eight; more decompositions exist.
