Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589588, here are decompositions:

127 + 31589461 = 31589588
181 + 31589407 = 31589588
211 + 31589377 = 31589588
229 + 31589359 = 31589588
271 + 31589317 = 31589588
337 + 31589251 = 31589588
421 + 31589167 = 31589588
571 + 31589017 = 31589588

Showing the first eight; more decompositions exist.
