Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589530, here are decompositions:

17 + 31589513 = 31589530
47 + 31589483 = 31589530
107 + 31589423 = 31589530
191 + 31589339 = 31589530
197 + 31589333 = 31589530
227 + 31589303 = 31589530
233 + 31589297 = 31589530
239 + 31589291 = 31589530

Showing the first eight; more decompositions exist.
