Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574032, here are decompositions:

11 + 31574021 = 31574032
71 + 31573961 = 31574032
101 + 31573931 = 31574032
173 + 31573859 = 31574032
179 + 31573853 = 31574032
239 + 31573793 = 31574032
353 + 31573679 = 31574032
389 + 31573643 = 31574032

Showing the first eight; more decompositions exist.
