Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172748, here are decompositions:

7 + 172741 = 172748
31 + 172717 = 172748
61 + 172687 = 172748
67 + 172681 = 172748
151 + 172597 = 172748
229 + 172519 = 172748
241 + 172507 = 172748
307 + 172441 = 172748

Showing the first eight; more decompositions exist.
