Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585076, here are decompositions:

43 + 31585033 = 31585076
109 + 31584967 = 31585076
223 + 31584853 = 31585076
307 + 31584769 = 31585076
373 + 31584703 = 31585076
379 + 31584697 = 31585076
409 + 31584667 = 31585076
463 + 31584613 = 31585076

Showing the first eight; more decompositions exist.
