Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589836, here are decompositions:

17 + 31589819 = 31589836
59 + 31589777 = 31589836
269 + 31589567 = 31589836
353 + 31589483 = 31589836
503 + 31589333 = 31589836
653 + 31589183 = 31589836
809 + 31589027 = 31589836
857 + 31588979 = 31589836

Showing the first eight; more decompositions exist.
