Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607664, here are decompositions:

83 + 31607581 = 31607664
113 + 31607551 = 31607664
191 + 31607473 = 31607664
241 + 31607423 = 31607664
307 + 31607357 = 31607664
337 + 31607327 = 31607664
367 + 31607297 = 31607664
373 + 31607291 = 31607664

Showing the first eight; more decompositions exist.
