Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586008, here are decompositions:

5 + 31586003 = 31586008
11 + 31585997 = 31586008
29 + 31585979 = 31586008
71 + 31585937 = 31586008
191 + 31585817 = 31586008
197 + 31585811 = 31586008
227 + 31585781 = 31586008
257 + 31585751 = 31586008

Showing the first eight; more decompositions exist.
