Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586296, here are decompositions:

23 + 31586273 = 31586296
59 + 31586237 = 31586296
149 + 31586147 = 31586296
239 + 31586057 = 31586296
293 + 31586003 = 31586296
317 + 31585979 = 31586296
359 + 31585937 = 31586296
479 + 31585817 = 31586296

Showing the first eight; more decompositions exist.
