Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485016, here are decompositions:

23 + 31484993 = 31485016
113 + 31484903 = 31485016
179 + 31484837 = 31485016
239 + 31484777 = 31485016
263 + 31484753 = 31485016
317 + 31484699 = 31485016
389 + 31484627 = 31485016
503 + 31484513 = 31485016

Showing the first eight; more decompositions exist.
