Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596766, here are decompositions:

17 + 31596749 = 31596766
23 + 31596743 = 31596766
53 + 31596713 = 31596766
59 + 31596707 = 31596766
269 + 31596497 = 31596766
293 + 31596473 = 31596766
347 + 31596419 = 31596766
353 + 31596413 = 31596766

Showing the first eight; more decompositions exist.
