Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164930, here are decompositions:

19 + 164911 = 164930
37 + 164893 = 164930
109 + 164821 = 164930
163 + 164767 = 164930
223 + 164707 = 164930
229 + 164701 = 164930
277 + 164653 = 164930
307 + 164623 = 164930

Showing the first eight; more decompositions exist.
