Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175228, here are decompositions:

17 + 175211 = 175228
149 + 175079 = 175228
167 + 175061 = 175228
239 + 174989 = 175228
269 + 174959 = 175228
311 + 174917 = 175228
461 + 174767 = 175228
467 + 174761 = 175228

Showing the first eight; more decompositions exist.
