Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585036, here are decompositions:

3 + 31585033 = 31585036
17 + 31585019 = 31585036
83 + 31584953 = 31585036
89 + 31584947 = 31585036
149 + 31584887 = 31585036
167 + 31584869 = 31585036
227 + 31584809 = 31585036
239 + 31584797 = 31585036

Showing the first eight; more decompositions exist.
