Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589566, here are decompositions:

5 + 31589561 = 31589566
53 + 31589513 = 31589566
83 + 31589483 = 31589566
227 + 31589339 = 31589566
233 + 31589333 = 31589566
263 + 31589303 = 31589566
269 + 31589297 = 31589566
383 + 31589183 = 31589566

Showing the first eight; more decompositions exist.
