Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475104, here are decompositions:

5 + 31475099 = 31475104
107 + 31474997 = 31475104
173 + 31474931 = 31475104
383 + 31474721 = 31475104
431 + 31474673 = 31475104
503 + 31474601 = 31475104
701 + 31474403 = 31475104
761 + 31474343 = 31475104

Showing the first eight; more decompositions exist.
