Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501314, here are decompositions:

11 + 31501303 = 31501314
67 + 31501247 = 31501314
83 + 31501231 = 31501314
113 + 31501201 = 31501314
197 + 31501117 = 31501314
223 + 31501091 = 31501314
233 + 31501081 = 31501314
277 + 31501037 = 31501314

Showing the first eight; more decompositions exist.
