Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585304, here are decompositions:

43 + 31585261 = 31585304
211 + 31585093 = 31585304
271 + 31585033 = 31585304
337 + 31584967 = 31585304
397 + 31584907 = 31585304
547 + 31584757 = 31585304
601 + 31584703 = 31585304
607 + 31584697 = 31585304

Showing the first eight; more decompositions exist.
