Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485010, here are decompositions:

17 + 31484993 = 31485010
107 + 31484903 = 31485010
173 + 31484837 = 31485010
233 + 31484777 = 31485010
239 + 31484771 = 31485010
257 + 31484753 = 31485010
269 + 31484741 = 31485010
311 + 31484699 = 31485010

Showing the first eight; more decompositions exist.
