Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471966, here are decompositions:

59 + 31471907 = 31471966
83 + 31471883 = 31471966
167 + 31471799 = 31471966
179 + 31471787 = 31471966
263 + 31471703 = 31471966
269 + 31471697 = 31471966
389 + 31471577 = 31471966
443 + 31471523 = 31471966

Showing the first eight; more decompositions exist.
