Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586862, here are decompositions:

23 + 31586839 = 31586862
53 + 31586809 = 31586862
59 + 31586803 = 31586862
71 + 31586791 = 31586862
163 + 31586699 = 31586862
173 + 31586689 = 31586862
191 + 31586671 = 31586862
193 + 31586669 = 31586862

Showing the first eight; more decompositions exist.
