Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477418, here are decompositions:

19 + 31477399 = 31477418
67 + 31477351 = 31477418
97 + 31477321 = 31477418
127 + 31477291 = 31477418
211 + 31477207 = 31477418
277 + 31477141 = 31477418
307 + 31477111 = 31477418
367 + 31477051 = 31477418

Showing the first eight; more decompositions exist.
