Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585698, here are decompositions:

7 + 31585691 = 31585698
31 + 31585667 = 31585698
61 + 31585637 = 31585698
101 + 31585597 = 31585698
127 + 31585571 = 31585698
149 + 31585549 = 31585698
181 + 31585517 = 31585698
197 + 31585501 = 31585698

Showing the first eight; more decompositions exist.
