Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593584, here are decompositions:

13 + 31593571 = 31593584
31 + 31593553 = 31593584
67 + 31593517 = 31593584
73 + 31593511 = 31593584
193 + 31593391 = 31593584
241 + 31593343 = 31593584
271 + 31593313 = 31593584
277 + 31593307 = 31593584

Showing the first eight; more decompositions exist.
