Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586074, here are decompositions:

17 + 31586057 = 31586074
71 + 31586003 = 31586074
101 + 31585973 = 31586074
137 + 31585937 = 31586074
251 + 31585823 = 31586074
257 + 31585817 = 31586074
263 + 31585811 = 31586074
293 + 31585781 = 31586074

Showing the first eight; more decompositions exist.
