Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586464, here are decompositions:

3 + 31586461 = 31586464
17 + 31586447 = 31586464
113 + 31586351 = 31586464
191 + 31586273 = 31586464
227 + 31586237 = 31586464
293 + 31586171 = 31586464
317 + 31586147 = 31586464
461 + 31586003 = 31586464

Showing the first eight; more decompositions exist.
