Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589636, here are decompositions:

3 + 31589633 = 31589636
97 + 31589539 = 31589636
163 + 31589473 = 31589636
229 + 31589407 = 31589636
277 + 31589359 = 31589636
283 + 31589353 = 31589636
307 + 31589329 = 31589636
349 + 31589287 = 31589636

Showing the first eight; more decompositions exist.
