Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475692, here are decompositions:

11 + 31475681 = 31475692
23 + 31475669 = 31475692
113 + 31475579 = 31475692
233 + 31475459 = 31475692
239 + 31475453 = 31475692
263 + 31475429 = 31475692
449 + 31475243 = 31475692
461 + 31475231 = 31475692

Showing the first eight; more decompositions exist.
