Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585046, here are decompositions:

13 + 31585033 = 31585046
79 + 31584967 = 31585046
139 + 31584907 = 31585046
193 + 31584853 = 31585046
223 + 31584823 = 31585046
277 + 31584769 = 31585046
349 + 31584697 = 31585046
379 + 31584667 = 31585046

Showing the first eight; more decompositions exist.
