Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470892, here are decompositions:

3 + 31470889 = 31470892
23 + 31470869 = 31470892
29 + 31470863 = 31470892
59 + 31470833 = 31470892
191 + 31470701 = 31470892
239 + 31470653 = 31470892
251 + 31470641 = 31470892
263 + 31470629 = 31470892

Showing the first eight; more decompositions exist.
