Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574074, here are decompositions:

3 + 31574071 = 31574074
53 + 31574021 = 31574074
107 + 31573967 = 31574074
113 + 31573961 = 31574074
227 + 31573847 = 31574074
251 + 31573823 = 31574074
281 + 31573793 = 31574074
317 + 31573757 = 31574074

Showing the first eight; more decompositions exist.
