Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597694, here are decompositions:

43 + 31597651 = 31597694
211 + 31597483 = 31597694
223 + 31597471 = 31597694
241 + 31597453 = 31597694
277 + 31597417 = 31597694
283 + 31597411 = 31597694
433 + 31597261 = 31597694
463 + 31597231 = 31597694

Showing the first eight; more decompositions exist.
