Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574112, here are decompositions:

5 + 31574107 = 31574112
13 + 31574099 = 31574112
19 + 31574093 = 31574112
41 + 31574071 = 31574112
71 + 31574041 = 31574112
113 + 31573999 = 31574112
151 + 31573961 = 31574112
181 + 31573931 = 31574112

Showing the first eight; more decompositions exist.
