Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589524, here are decompositions:

11 + 31589513 = 31589524
41 + 31589483 = 31589524
101 + 31589423 = 31589524
191 + 31589333 = 31589524
227 + 31589297 = 31589524
233 + 31589291 = 31589524
467 + 31589057 = 31589524
677 + 31588847 = 31589524

Showing the first eight; more decompositions exist.
