Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164918, here are decompositions:

7 + 164911 = 164918
37 + 164881 = 164918
79 + 164839 = 164918
97 + 164821 = 164918
109 + 164809 = 164918
151 + 164767 = 164918
211 + 164707 = 164918
241 + 164677 = 164918

Showing the first eight; more decompositions exist.
