Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475698, here are decompositions:

17 + 31475681 = 31475698
29 + 31475669 = 31475698
101 + 31475597 = 31475698
227 + 31475471 = 31475698
239 + 31475459 = 31475698
269 + 31475429 = 31475698
311 + 31475387 = 31475698
467 + 31475231 = 31475698

Showing the first eight; more decompositions exist.
