Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498514, here are decompositions:

43 + 31498471 = 31498514
241 + 31498273 = 31498514
631 + 31497883 = 31498514
643 + 31497871 = 31498514
757 + 31497757 = 31498514
787 + 31497727 = 31498514
877 + 31497637 = 31498514
937 + 31497577 = 31498514

Showing the first eight; more decompositions exist.
