Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135930, here are decompositions:

17 + 135913 = 135930
19 + 135911 = 135930
31 + 135899 = 135930
37 + 135893 = 135930
43 + 135887 = 135930
71 + 135859 = 135930
79 + 135851 = 135930
89 + 135841 = 135930

Showing the first eight; more decompositions exist.
