Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588726, here are decompositions:

17 + 31588709 = 31588726
47 + 31588679 = 31588726
53 + 31588673 = 31588726
83 + 31588643 = 31588726
233 + 31588493 = 31588726
263 + 31588463 = 31588726
359 + 31588367 = 31588726
419 + 31588307 = 31588726

Showing the first eight; more decompositions exist.
