Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477214, here are decompositions:

7 + 31477207 = 31477214
73 + 31477141 = 31477214
103 + 31477111 = 31477214
151 + 31477063 = 31477214
157 + 31477057 = 31477214
163 + 31477051 = 31477214
193 + 31477021 = 31477214
283 + 31476931 = 31477214

Showing the first eight; more decompositions exist.
