Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499110, here are decompositions:

3 + 31499107 = 31499110
47 + 31499063 = 31499110
53 + 31499057 = 31499110
89 + 31499021 = 31499110
107 + 31499003 = 31499110
179 + 31498931 = 31499110
197 + 31498913 = 31499110
257 + 31498853 = 31499110

Showing the first eight; more decompositions exist.
