Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596894, here are decompositions:

5 + 31596889 = 31596894
11 + 31596883 = 31596894
13 + 31596881 = 31596894
37 + 31596857 = 31596894
47 + 31596847 = 31596894
73 + 31596821 = 31596894
97 + 31596797 = 31596894
101 + 31596793 = 31596894

Showing the first eight; more decompositions exist.
