Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184972, here are decompositions:

3 + 184969 = 184972
5 + 184967 = 184972
23 + 184949 = 184972
59 + 184913 = 184972
71 + 184901 = 184972
113 + 184859 = 184972
149 + 184823 = 184972
239 + 184733 = 184972

Showing the first eight; more decompositions exist.
