Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589806, here are decompositions:

29 + 31589777 = 31589806
47 + 31589759 = 31589806
113 + 31589693 = 31589806
173 + 31589633 = 31589806
239 + 31589567 = 31589806
293 + 31589513 = 31589806
383 + 31589423 = 31589806
467 + 31589339 = 31589806

Showing the first eight; more decompositions exist.
