Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585052, here are decompositions:

19 + 31585033 = 31585052
151 + 31584901 = 31585052
199 + 31584853 = 31585052
223 + 31584829 = 31585052
229 + 31584823 = 31585052
283 + 31584769 = 31585052
349 + 31584703 = 31585052
439 + 31584613 = 31585052

Showing the first eight; more decompositions exist.
