Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475368, here are decompositions:

47 + 31475321 = 31475368
137 + 31475231 = 31475368
179 + 31475189 = 31475368
227 + 31475141 = 31475368
257 + 31475111 = 31475368
269 + 31475099 = 31475368
359 + 31475009 = 31475368
647 + 31474721 = 31475368

Showing the first eight; more decompositions exist.
