Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585984, here are decompositions:

5 + 31585979 = 31585984
11 + 31585973 = 31585984
47 + 31585937 = 31585984
167 + 31585817 = 31585984
173 + 31585811 = 31585984
233 + 31585751 = 31585984
293 + 31585691 = 31585984
317 + 31585667 = 31585984

Showing the first eight; more decompositions exist.
