Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586596, here are decompositions:

5 + 31586591 = 31586596
17 + 31586579 = 31586596
53 + 31586543 = 31586596
59 + 31586537 = 31586596
113 + 31586483 = 31586596
149 + 31586447 = 31586596
257 + 31586339 = 31586596
359 + 31586237 = 31586596

Showing the first eight; more decompositions exist.
