Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585734, here are decompositions:

43 + 31585691 = 31585734
67 + 31585667 = 31585734
71 + 31585663 = 31585734
97 + 31585637 = 31585734
137 + 31585597 = 31585734
151 + 31585583 = 31585734
157 + 31585577 = 31585734
163 + 31585571 = 31585734

Showing the first eight; more decompositions exist.
