Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586896, here are decompositions:

17 + 31586879 = 31586896
83 + 31586813 = 31586896
179 + 31586717 = 31586896
197 + 31586699 = 31586896
227 + 31586669 = 31586896
269 + 31586627 = 31586896
317 + 31586579 = 31586896
353 + 31586543 = 31586896

Showing the first eight; more decompositions exist.
