Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508264, here are decompositions:

31 + 31508233 = 31508264
37 + 31508227 = 31508264
61 + 31508203 = 31508264
157 + 31508107 = 31508264
163 + 31508101 = 31508264
181 + 31508083 = 31508264
283 + 31507981 = 31508264
313 + 31507951 = 31508264

Showing the first eight; more decompositions exist.
