Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585684, here are decompositions:

17 + 31585667 = 31585684
47 + 31585637 = 31585684
71 + 31585613 = 31585684
101 + 31585583 = 31585684
107 + 31585577 = 31585684
113 + 31585571 = 31585684
167 + 31585517 = 31585684
191 + 31585493 = 31585684

Showing the first eight; more decompositions exist.
