Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601694, here are decompositions:

23 + 31601671 = 31601694
43 + 31601651 = 31601694
127 + 31601567 = 31601694
167 + 31601527 = 31601694
181 + 31601513 = 31601694
277 + 31601417 = 31601694
283 + 31601411 = 31601694
337 + 31601357 = 31601694

Showing the first eight; more decompositions exist.
