Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585024, here are decompositions:

5 + 31585019 = 31585024
71 + 31584953 = 31585024
137 + 31584887 = 31585024
227 + 31584797 = 31585024
311 + 31584713 = 31585024
593 + 31584431 = 31585024
617 + 31584407 = 31585024
641 + 31584383 = 31585024

Showing the first eight; more decompositions exist.
