Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586466, here are decompositions:

5 + 31586461 = 31586466
19 + 31586447 = 31586466
59 + 31586407 = 31586466
89 + 31586377 = 31586466
127 + 31586339 = 31586466
179 + 31586287 = 31586466
193 + 31586273 = 31586466
229 + 31586237 = 31586466

Showing the first eight; more decompositions exist.
