Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574118, here are decompositions:

11 + 31574107 = 31574118
19 + 31574099 = 31574118
47 + 31574071 = 31574118
71 + 31574047 = 31574118
97 + 31574021 = 31574118
151 + 31573967 = 31574118
157 + 31573961 = 31574118
271 + 31573847 = 31574118

Showing the first eight; more decompositions exist.
