Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574104, here are decompositions:

5 + 31574099 = 31574104
11 + 31574093 = 31574104
83 + 31574021 = 31574104
137 + 31573967 = 31574104
173 + 31573931 = 31574104
251 + 31573853 = 31574104
257 + 31573847 = 31574104
281 + 31573823 = 31574104

Showing the first eight; more decompositions exist.
