Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475710, here are decompositions:

29 + 31475681 = 31475710
41 + 31475669 = 31475710
113 + 31475597 = 31475710
131 + 31475579 = 31475710
239 + 31475471 = 31475710
251 + 31475459 = 31475710
257 + 31475453 = 31475710
281 + 31475429 = 31475710

Showing the first eight; more decompositions exist.
