Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574056, here are decompositions:

89 + 31573967 = 31574056
197 + 31573859 = 31574056
233 + 31573823 = 31574056
263 + 31573793 = 31574056
359 + 31573697 = 31574056
557 + 31573499 = 31574056
593 + 31573463 = 31574056
797 + 31573259 = 31574056

Showing the first eight; more decompositions exist.
