Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589494, here are decompositions:

11 + 31589483 = 31589494
71 + 31589423 = 31589494
173 + 31589321 = 31589494
191 + 31589303 = 31589494
197 + 31589297 = 31589494
311 + 31589183 = 31589494
467 + 31589027 = 31589494
647 + 31588847 = 31589494

Showing the first eight; more decompositions exist.
