Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586822, here are decompositions:

13 + 31586809 = 31586822
19 + 31586803 = 31586822
31 + 31586791 = 31586822
79 + 31586743 = 31586822
103 + 31586719 = 31586822
151 + 31586671 = 31586822
313 + 31586509 = 31586822
349 + 31586473 = 31586822

Showing the first eight; more decompositions exist.
