Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477066, here are decompositions:

3 + 31477063 = 31477066
107 + 31476959 = 31477066
149 + 31476917 = 31477066
443 + 31476623 = 31477066
479 + 31476587 = 31477066
557 + 31476509 = 31477066
617 + 31476449 = 31477066
653 + 31476413 = 31477066

Showing the first eight; more decompositions exist.
