Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601968, here are decompositions:

71 + 31601897 = 31601968
131 + 31601837 = 31601968
149 + 31601819 = 31601968
257 + 31601711 = 31601968
269 + 31601699 = 31601968
317 + 31601651 = 31601968
401 + 31601567 = 31601968
479 + 31601489 = 31601968

Showing the first eight; more decompositions exist.
