Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475350, here are decompositions:

29 + 31475321 = 31475350
107 + 31475243 = 31475350
191 + 31475159 = 31475350
239 + 31475111 = 31475350
251 + 31475099 = 31475350
281 + 31475069 = 31475350
353 + 31474997 = 31475350
419 + 31474931 = 31475350

Showing the first eight; more decompositions exist.
