Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172712, here are decompositions:

3 + 172709 = 172712
31 + 172681 = 172712
79 + 172633 = 172712
109 + 172603 = 172712
139 + 172573 = 172712
151 + 172561 = 172712
193 + 172519 = 172712
223 + 172489 = 172712

Showing the first eight; more decompositions exist.
