Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586106, here are decompositions:

5 + 31586101 = 31586106
29 + 31586077 = 31586106
47 + 31586059 = 31586106
53 + 31586053 = 31586106
103 + 31586003 = 31586106
109 + 31585997 = 31586106
127 + 31585979 = 31586106
257 + 31585849 = 31586106

Showing the first eight; more decompositions exist.
