Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585106, here are decompositions:

13 + 31585093 = 31585106
73 + 31585033 = 31585106
139 + 31584967 = 31585106
199 + 31584907 = 31585106
277 + 31584829 = 31585106
283 + 31584823 = 31585106
337 + 31584769 = 31585106
349 + 31584757 = 31585106

Showing the first eight; more decompositions exist.
