Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31922, here are decompositions:

31 + 31891 = 31922
73 + 31849 = 31922
151 + 31771 = 31922
181 + 31741 = 31922
193 + 31729 = 31922
199 + 31723 = 31922
223 + 31699 = 31922
349 + 31573 = 31922

Showing the first eight; more decompositions exist.
