Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596900, here are decompositions:

11 + 31596889 = 31596900
17 + 31596883 = 31596900
19 + 31596881 = 31596900
43 + 31596857 = 31596900
53 + 31596847 = 31596900
61 + 31596839 = 31596900
79 + 31596821 = 31596900
103 + 31596797 = 31596900

Showing the first eight; more decompositions exist.
