Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477182, here are decompositions:

19 + 31477163 = 31477182
41 + 31477141 = 31477182
71 + 31477111 = 31477182
83 + 31477099 = 31477182
103 + 31477079 = 31477182
131 + 31477051 = 31477182
223 + 31476959 = 31477182
251 + 31476931 = 31477182

Showing the first eight; more decompositions exist.
