Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586924, here are decompositions:

3 + 31586921 = 31586924
181 + 31586743 = 31586924
277 + 31586647 = 31586924
307 + 31586617 = 31586924
463 + 31586461 = 31586924
547 + 31586377 = 31586924
613 + 31586311 = 31586924
643 + 31586281 = 31586924

Showing the first eight; more decompositions exist.
