Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508234, here are decompositions:

3 + 31508231 = 31508234
7 + 31508227 = 31508234
31 + 31508203 = 31508234
127 + 31508107 = 31508234
151 + 31508083 = 31508234
157 + 31508077 = 31508234
283 + 31507951 = 31508234
313 + 31507921 = 31508234

Showing the first eight; more decompositions exist.
