Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586334, here are decompositions:

23 + 31586311 = 31586334
47 + 31586287 = 31586334
53 + 31586281 = 31586334
61 + 31586273 = 31586334
97 + 31586237 = 31586334
163 + 31586171 = 31586334
193 + 31586141 = 31586334
233 + 31586101 = 31586334

Showing the first eight; more decompositions exist.
