Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172724, here are decompositions:

3 + 172721 = 172724
7 + 172717 = 172724
37 + 172687 = 172724
43 + 172681 = 172724
61 + 172663 = 172724
67 + 172657 = 172724
127 + 172597 = 172724
151 + 172573 = 172724

Showing the first eight; more decompositions exist.
