Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499032, here are decompositions:

11 + 31499021 = 31499032
29 + 31499003 = 31499032
41 + 31498991 = 31499032
83 + 31498949 = 31499032
101 + 31498931 = 31499032
179 + 31498853 = 31499032
269 + 31498763 = 31499032
491 + 31498541 = 31499032

Showing the first eight; more decompositions exist.
