Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172948, here are decompositions:

71 + 172877 = 172948
89 + 172859 = 172948
197 + 172751 = 172948
227 + 172721 = 172948
239 + 172709 = 172948
359 + 172589 = 172948
431 + 172517 = 172948
509 + 172439 = 172948

Showing the first eight; more decompositions exist.
