Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508274, here are decompositions:

41 + 31508233 = 31508274
43 + 31508231 = 31508274
47 + 31508227 = 31508274
71 + 31508203 = 31508274
97 + 31508177 = 31508274
103 + 31508171 = 31508274
131 + 31508143 = 31508274
167 + 31508107 = 31508274

Showing the first eight; more decompositions exist.
