Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589656, here are decompositions:

23 + 31589633 = 31589656
89 + 31589567 = 31589656
173 + 31589483 = 31589656
233 + 31589423 = 31589656
317 + 31589339 = 31589656
353 + 31589303 = 31589656
359 + 31589297 = 31589656
557 + 31589099 = 31589656

Showing the first eight; more decompositions exist.
