Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586202, here are decompositions:

31 + 31586171 = 31586202
61 + 31586141 = 31586202
71 + 31586131 = 31586202
101 + 31586101 = 31586202
149 + 31586053 = 31586202
199 + 31586003 = 31586202
223 + 31585979 = 31586202
229 + 31585973 = 31586202

Showing the first eight; more decompositions exist.
