Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585674, here are decompositions:

7 + 31585667 = 31585674
11 + 31585663 = 31585674
37 + 31585637 = 31585674
61 + 31585613 = 31585674
97 + 31585577 = 31585674
103 + 31585571 = 31585674
137 + 31585537 = 31585674
157 + 31585517 = 31585674

Showing the first eight; more decompositions exist.
