Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498996, here are decompositions:

3 + 31498993 = 31498996
5 + 31498991 = 31498996
29 + 31498967 = 31498996
47 + 31498949 = 31498996
83 + 31498913 = 31498996
149 + 31498847 = 31498996
167 + 31498829 = 31498996
233 + 31498763 = 31498996

Showing the first eight; more decompositions exist.
