Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586118, here are decompositions:

17 + 31586101 = 31586118
41 + 31586077 = 31586118
59 + 31586059 = 31586118
61 + 31586057 = 31586118
139 + 31585979 = 31586118
181 + 31585937 = 31586118
229 + 31585889 = 31586118
269 + 31585849 = 31586118

Showing the first eight; more decompositions exist.
