Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525794, here are decompositions:

7 + 31525787 = 31525794
11 + 31525783 = 31525794
17 + 31525777 = 31525794
23 + 31525771 = 31525794
31 + 31525763 = 31525794
71 + 31525723 = 31525794
107 + 31525687 = 31525794
137 + 31525657 = 31525794

Showing the first eight; more decompositions exist.
