Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173522, here are decompositions:

31 + 173491 = 173522
163 + 173359 = 173522
229 + 173293 = 173522
313 + 173209 = 173522
331 + 173191 = 173522
373 + 173149 = 173522
463 + 173059 = 173522
499 + 173023 = 173522

Showing the first eight; more decompositions exist.
