Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484806, here are decompositions:

5 + 31484801 = 31484806
29 + 31484777 = 31484806
53 + 31484753 = 31484806
107 + 31484699 = 31484806
179 + 31484627 = 31484806
263 + 31484543 = 31484806
293 + 31484513 = 31484806
389 + 31484417 = 31484806

Showing the first eight; more decompositions exist.
