Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42712, here are decompositions:

3 + 42709 = 42712
11 + 42701 = 42712
23 + 42689 = 42712
29 + 42683 = 42712
71 + 42641 = 42712
101 + 42611 = 42712
179 + 42533 = 42712
239 + 42473 = 42712

Showing the first eight; more decompositions exist.
