Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169930, here are decompositions:

11 + 169919 = 169930
17 + 169913 = 169930
41 + 169889 = 169930
71 + 169859 = 169930
107 + 169823 = 169930
113 + 169817 = 169930
179 + 169751 = 169930
197 + 169733 = 169930

Showing the first eight; more decompositions exist.
