Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477334, here are decompositions:

13 + 31477321 = 31477334
43 + 31477291 = 31477334
127 + 31477207 = 31477334
193 + 31477141 = 31477334
223 + 31477111 = 31477334
271 + 31477063 = 31477334
277 + 31477057 = 31477334
283 + 31477051 = 31477334

Showing the first eight; more decompositions exist.
