Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574184, here are decompositions:

11 + 31574173 = 31574184
53 + 31574131 = 31574184
113 + 31574071 = 31574184
137 + 31574047 = 31574184
163 + 31574021 = 31574184
223 + 31573961 = 31574184
227 + 31573957 = 31574184
331 + 31573853 = 31574184

Showing the first eight; more decompositions exist.
