Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558914, here are decompositions:

17 + 31558897 = 31558914
31 + 31558883 = 31558914
67 + 31558847 = 31558914
71 + 31558843 = 31558914
83 + 31558831 = 31558914
173 + 31558741 = 31558914
181 + 31558733 = 31558914
197 + 31558717 = 31558914

Showing the first eight; more decompositions exist.
