Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499108, here are decompositions:

31 + 31499077 = 31499108
211 + 31498897 = 31499108
229 + 31498879 = 31499108
241 + 31498867 = 31499108
271 + 31498837 = 31499108
367 + 31498741 = 31499108
829 + 31498279 = 31499108
919 + 31498189 = 31499108

Showing the first eight; more decompositions exist.
