Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585936, here are decompositions:

47 + 31585889 = 31585936
113 + 31585823 = 31585936
269 + 31585667 = 31585936
353 + 31585583 = 31585936
359 + 31585577 = 31585936
419 + 31585517 = 31585936
443 + 31585493 = 31585936
467 + 31585469 = 31585936

Showing the first eight; more decompositions exist.
