Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599584, here are decompositions:

31 + 31599553 = 31599584
97 + 31599487 = 31599584
271 + 31599313 = 31599584
277 + 31599307 = 31599584
337 + 31599247 = 31599584
631 + 31598953 = 31599584
661 + 31598923 = 31599584
673 + 31598911 = 31599584

Showing the first eight; more decompositions exist.
