Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574016, here are decompositions:

17 + 31573999 = 31574016
59 + 31573957 = 31574016
157 + 31573859 = 31574016
163 + 31573853 = 31574016
193 + 31573823 = 31574016
197 + 31573819 = 31574016
223 + 31573793 = 31574016
263 + 31573753 = 31574016

Showing the first eight; more decompositions exist.
