Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450274, here are decompositions:

3 + 31450271 = 31450274
67 + 31450207 = 31450274
157 + 31450117 = 31450274
181 + 31450093 = 31450274
241 + 31450033 = 31450274
283 + 31449991 = 31450274
307 + 31449967 = 31450274
337 + 31449937 = 31450274

Showing the first eight; more decompositions exist.
