Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508096, here are decompositions:

3 + 31508093 = 31508096
13 + 31508083 = 31508096
19 + 31508077 = 31508096
79 + 31508017 = 31508096
157 + 31507939 = 31508096
199 + 31507897 = 31508096
307 + 31507789 = 31508096
397 + 31507699 = 31508096

Showing the first eight; more decompositions exist.
