Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586922, here are decompositions:

19 + 31586903 = 31586922
43 + 31586879 = 31586922
53 + 31586869 = 31586922
83 + 31586839 = 31586922
109 + 31586813 = 31586922
113 + 31586809 = 31586922
131 + 31586791 = 31586922
179 + 31586743 = 31586922

Showing the first eight; more decompositions exist.
