Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574116, here are decompositions:

17 + 31574099 = 31574116
23 + 31574093 = 31574116
149 + 31573967 = 31574116
257 + 31573859 = 31574116
263 + 31573853 = 31574116
269 + 31573847 = 31574116
293 + 31573823 = 31574116
359 + 31573757 = 31574116

Showing the first eight; more decompositions exist.
