Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484956, here are decompositions:

53 + 31484903 = 31484956
179 + 31484777 = 31484956
257 + 31484699 = 31484956
443 + 31484513 = 31484956
593 + 31484363 = 31484956
617 + 31484339 = 31484956
653 + 31484303 = 31484956
719 + 31484237 = 31484956

Showing the first eight; more decompositions exist.
