Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499896, here are decompositions:

3 + 31499893 = 31499896
53 + 31499843 = 31499896
359 + 31499537 = 31499896
509 + 31499387 = 31499896
569 + 31499327 = 31499896
587 + 31499309 = 31499896
599 + 31499297 = 31499896
839 + 31499057 = 31499896

Showing the first eight; more decompositions exist.
