Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475326, here are decompositions:

5 + 31475321 = 31475326
83 + 31475243 = 31475326
137 + 31475189 = 31475326
167 + 31475159 = 31475326
227 + 31475099 = 31475326
257 + 31475069 = 31475326
317 + 31475009 = 31475326
563 + 31474763 = 31475326

Showing the first eight; more decompositions exist.
