Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586892, here are decompositions:

13 + 31586879 = 31586892
23 + 31586869 = 31586892
53 + 31586839 = 31586892
79 + 31586813 = 31586892
83 + 31586809 = 31586892
89 + 31586803 = 31586892
101 + 31586791 = 31586892
149 + 31586743 = 31586892

Showing the first eight; more decompositions exist.
