Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585704, here are decompositions:

13 + 31585691 = 31585704
37 + 31585667 = 31585704
41 + 31585663 = 31585704
67 + 31585637 = 31585704
107 + 31585597 = 31585704
127 + 31585577 = 31585704
167 + 31585537 = 31585704
211 + 31585493 = 31585704

Showing the first eight; more decompositions exist.
