Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601662, here are decompositions:

11 + 31601651 = 31601662
149 + 31601513 = 31601662
173 + 31601489 = 31601662
251 + 31601411 = 31601662
269 + 31601393 = 31601662
563 + 31601099 = 31601662
839 + 31600823 = 31601662
863 + 31600799 = 31601662

Showing the first eight; more decompositions exist.
