Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501266, here are decompositions:

19 + 31501247 = 31501266
37 + 31501229 = 31501266
47 + 31501219 = 31501266
67 + 31501199 = 31501266
149 + 31501117 = 31501266
227 + 31501039 = 31501266
229 + 31501037 = 31501266
257 + 31501009 = 31501266

Showing the first eight; more decompositions exist.
