Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601682, here are decompositions:

11 + 31601671 = 31601682
31 + 31601651 = 31601682
53 + 31601629 = 31601682
113 + 31601569 = 31601682
131 + 31601551 = 31601682
173 + 31601509 = 31601682
193 + 31601489 = 31601682
271 + 31601411 = 31601682

Showing the first eight; more decompositions exist.
