Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586082, here are decompositions:

5 + 31586077 = 31586082
23 + 31586059 = 31586082
29 + 31586053 = 31586082
79 + 31586003 = 31586082
103 + 31585979 = 31586082
109 + 31585973 = 31586082
179 + 31585903 = 31586082
193 + 31585889 = 31586082

Showing the first eight; more decompositions exist.
