Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596930, here are decompositions:

7 + 31596923 = 31596930
17 + 31596913 = 31596930
23 + 31596907 = 31596930
31 + 31596899 = 31596930
41 + 31596889 = 31596930
47 + 31596883 = 31596930
73 + 31596857 = 31596930
83 + 31596847 = 31596930

Showing the first eight; more decompositions exist.
