Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475266, here are decompositions:

23 + 31475243 = 31475266
107 + 31475159 = 31475266
167 + 31475099 = 31475266
197 + 31475069 = 31475266
257 + 31475009 = 31475266
269 + 31474997 = 31475266
503 + 31474763 = 31475266
593 + 31474673 = 31475266

Showing the first eight; more decompositions exist.
