Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585376, here are decompositions:

7 + 31585369 = 31585376
37 + 31585339 = 31585376
283 + 31585093 = 31585376
409 + 31584967 = 31585376
523 + 31584853 = 31585376
547 + 31584829 = 31585376
607 + 31584769 = 31585376
619 + 31584757 = 31585376

Showing the first eight; more decompositions exist.
