Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589550, here are decompositions:

11 + 31589539 = 31589550
37 + 31589513 = 31589550
67 + 31589483 = 31589550
89 + 31589461 = 31589550
127 + 31589423 = 31589550
149 + 31589401 = 31589550
173 + 31589377 = 31589550
191 + 31589359 = 31589550

Showing the first eight; more decompositions exist.
