Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477416, here are decompositions:

17 + 31477399 = 31477416
37 + 31477379 = 31477416
67 + 31477349 = 31477416
127 + 31477289 = 31477416
317 + 31477099 = 31477416
337 + 31477079 = 31477416
349 + 31477067 = 31477416
353 + 31477063 = 31477416

Showing the first eight; more decompositions exist.
