Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586684, here are decompositions:

13 + 31586671 = 31586684
37 + 31586647 = 31586684
67 + 31586617 = 31586684
211 + 31586473 = 31586684
223 + 31586461 = 31586684
277 + 31586407 = 31586684
307 + 31586377 = 31586684
373 + 31586311 = 31586684

Showing the first eight; more decompositions exist.
