Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153930, here are decompositions:

17 + 153913 = 153930
19 + 153911 = 153930
41 + 153889 = 153930
43 + 153887 = 153930
53 + 153877 = 153930
59 + 153871 = 153930
89 + 153841 = 153930
113 + 153817 = 153930

Showing the first eight; more decompositions exist.
