Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477366, here are decompositions:

17 + 31477349 = 31477366
419 + 31476947 = 31477366
449 + 31476917 = 31477366
743 + 31476623 = 31477366
773 + 31476593 = 31477366
857 + 31476509 = 31477366
929 + 31476437 = 31477366
953 + 31476413 = 31477366

Showing the first eight; more decompositions exist.
