Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501996, here are decompositions:

17 + 31501979 = 31501996
59 + 31501937 = 31501996
83 + 31501913 = 31501996
89 + 31501907 = 31501996
173 + 31501823 = 31501996
269 + 31501727 = 31501996
563 + 31501433 = 31501996
569 + 31501427 = 31501996

Showing the first eight; more decompositions exist.
