Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171422, here are decompositions:

19 + 171403 = 171422
151 + 171271 = 171422
331 + 171091 = 171422
373 + 171049 = 171422
379 + 171043 = 171422
523 + 170899 = 171422
541 + 170881 = 171422
571 + 170851 = 171422

Showing the first eight; more decompositions exist.
