Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475716, here are decompositions:

3 + 31475713 = 31475716
47 + 31475669 = 31475716
137 + 31475579 = 31475716
227 + 31475489 = 31475716
257 + 31475459 = 31475716
263 + 31475453 = 31475716
557 + 31475159 = 31475716
617 + 31475099 = 31475716

Showing the first eight; more decompositions exist.
