Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585826, here are decompositions:

3 + 31585823 = 31585826
43 + 31585783 = 31585826
163 + 31585663 = 31585826
229 + 31585597 = 31585826
277 + 31585549 = 31585826
367 + 31585459 = 31585826
373 + 31585453 = 31585826
379 + 31585447 = 31585826

Showing the first eight; more decompositions exist.
