Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499926, here are decompositions:

5 + 31499921 = 31499926
83 + 31499843 = 31499926
389 + 31499537 = 31499926
467 + 31499459 = 31499926
599 + 31499327 = 31499926
617 + 31499309 = 31499926
659 + 31499267 = 31499926
743 + 31499183 = 31499926

Showing the first eight; more decompositions exist.
