Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574164, here are decompositions:

71 + 31574093 = 31574164
197 + 31573967 = 31574164
233 + 31573931 = 31574164
311 + 31573853 = 31574164
317 + 31573847 = 31574164
467 + 31573697 = 31574164
521 + 31573643 = 31574164
593 + 31573571 = 31574164

Showing the first eight; more decompositions exist.
