Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163930, here are decompositions:

3 + 163927 = 163930
29 + 163901 = 163930
47 + 163883 = 163930
59 + 163871 = 163930
71 + 163859 = 163930
83 + 163847 = 163930
89 + 163841 = 163930
149 + 163781 = 163930

Showing the first eight; more decompositions exist.
