Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499074, here are decompositions:

11 + 31499063 = 31499074
17 + 31499057 = 31499074
41 + 31499033 = 31499074
53 + 31499021 = 31499074
71 + 31499003 = 31499074
83 + 31498991 = 31499074
107 + 31498967 = 31499074
227 + 31498847 = 31499074

Showing the first eight; more decompositions exist.
