Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172892, here are decompositions:

43 + 172849 = 172892
151 + 172741 = 172892
211 + 172681 = 172892
229 + 172663 = 172892
331 + 172561 = 172892
373 + 172519 = 172892
541 + 172351 = 172892
571 + 172321 = 172892

Showing the first eight; more decompositions exist.
