Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586934, here are decompositions:

7 + 31586927 = 31586934
13 + 31586921 = 31586934
31 + 31586903 = 31586934
131 + 31586803 = 31586934
191 + 31586743 = 31586934
227 + 31586707 = 31586934
263 + 31586671 = 31586934
307 + 31586627 = 31586934

Showing the first eight; more decompositions exist.
