Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477672, here are decompositions:

3 + 31477669 = 31477672
89 + 31477583 = 31477672
101 + 31477571 = 31477672
293 + 31477379 = 31477672
383 + 31477289 = 31477672
491 + 31477181 = 31477672
509 + 31477163 = 31477672
593 + 31477079 = 31477672

Showing the first eight; more decompositions exist.
