Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477058, here are decompositions:

7 + 31477051 = 31477058
31 + 31477027 = 31477058
37 + 31477021 = 31477058
127 + 31476931 = 31477058
211 + 31476847 = 31477058
229 + 31476829 = 31477058
331 + 31476727 = 31477058
367 + 31476691 = 31477058

Showing the first eight; more decompositions exist.
