Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594960, here are decompositions:

29 + 31594931 = 31594960
41 + 31594919 = 31594960
53 + 31594907 = 31594960
83 + 31594877 = 31594960
149 + 31594811 = 31594960
191 + 31594769 = 31594960
233 + 31594727 = 31594960
269 + 31594691 = 31594960

Showing the first eight; more decompositions exist.
