Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30712, here are decompositions:

5 + 30707 = 30712
23 + 30689 = 30712
41 + 30671 = 30712
173 + 30539 = 30712
263 + 30449 = 30712
281 + 30431 = 30712
389 + 30323 = 30712
419 + 30293 = 30712

Showing the first eight; more decompositions exist.
