Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179930, here are decompositions:

7 + 179923 = 179930
13 + 179917 = 179930
31 + 179899 = 179930
97 + 179833 = 179930
103 + 179827 = 179930
109 + 179821 = 179930
151 + 179779 = 179930
181 + 179749 = 179930

Showing the first eight; more decompositions exist.
