Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184988, here are decompositions:

19 + 184969 = 184988
31 + 184957 = 184988
109 + 184879 = 184988
151 + 184837 = 184988
157 + 184831 = 184988
211 + 184777 = 184988
277 + 184711 = 184988
337 + 184651 = 184988

Showing the first eight; more decompositions exist.
