Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499068, here are decompositions:

5 + 31499063 = 31499068
11 + 31499057 = 31499068
47 + 31499021 = 31499068
101 + 31498967 = 31499068
137 + 31498931 = 31499068
239 + 31498829 = 31499068
257 + 31498811 = 31499068
509 + 31498559 = 31499068

Showing the first eight; more decompositions exist.
