Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477018, here are decompositions:

59 + 31476959 = 31477018
71 + 31476947 = 31477018
101 + 31476917 = 31477018
137 + 31476881 = 31477018
197 + 31476821 = 31477018
431 + 31476587 = 31477018
467 + 31476551 = 31477018
509 + 31476509 = 31477018

Showing the first eight; more decompositions exist.
