Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477384, here are decompositions:

5 + 31477379 = 31477384
83 + 31477301 = 31477384
317 + 31477067 = 31477384
467 + 31476917 = 31477384
503 + 31476881 = 31477384
563 + 31476821 = 31477384
641 + 31476743 = 31477384
761 + 31476623 = 31477384

Showing the first eight; more decompositions exist.
