Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586358, here are decompositions:

7 + 31586351 = 31586358
19 + 31586339 = 31586358
47 + 31586311 = 31586358
71 + 31586287 = 31586358
101 + 31586257 = 31586358
211 + 31586147 = 31586358
227 + 31586131 = 31586358
257 + 31586101 = 31586358

Showing the first eight; more decompositions exist.
