Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471134, here are decompositions:

11 + 31471123 = 31471134
41 + 31471093 = 31471134
43 + 31471091 = 31471134
83 + 31471051 = 31471134
103 + 31471031 = 31471134
127 + 31471007 = 31471134
137 + 31470997 = 31471134
157 + 31470977 = 31471134

Showing the first eight; more decompositions exist.
