Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532794, here are decompositions:

17 + 31532777 = 31532794
101 + 31532693 = 31532794
107 + 31532687 = 31532794
197 + 31532597 = 31532794
317 + 31532477 = 31532794
653 + 31532141 = 31532794
677 + 31532117 = 31532794
773 + 31532021 = 31532794

Showing the first eight; more decompositions exist.
