Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184980, here are decompositions:

11 + 184969 = 184980
13 + 184967 = 184980
23 + 184957 = 184980
31 + 184949 = 184980
67 + 184913 = 184980
79 + 184901 = 184980
101 + 184879 = 184980
137 + 184843 = 184980

Showing the first eight; more decompositions exist.
