Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586326, here are decompositions:

53 + 31586273 = 31586326
89 + 31586237 = 31586326
179 + 31586147 = 31586326
269 + 31586057 = 31586326
347 + 31585979 = 31586326
353 + 31585973 = 31586326
389 + 31585937 = 31586326
503 + 31585823 = 31586326

Showing the first eight; more decompositions exist.
