Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586410, here are decompositions:

3 + 31586407 = 31586410
59 + 31586351 = 31586410
71 + 31586339 = 31586410
137 + 31586273 = 31586410
173 + 31586237 = 31586410
239 + 31586171 = 31586410
263 + 31586147 = 31586410
269 + 31586141 = 31586410

Showing the first eight; more decompositions exist.
