Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11712, here are decompositions:

11 + 11701 = 11712
13 + 11699 = 11712
23 + 11689 = 11712
31 + 11681 = 11712
79 + 11633 = 11712
163 + 11549 = 11712
193 + 11519 = 11712
223 + 11489 = 11712

Showing the first eight; more decompositions exist.
