Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185984, here are decompositions:

13 + 185971 = 185984
37 + 185947 = 185984
61 + 185923 = 185984
67 + 185917 = 185984
151 + 185833 = 185984
163 + 185821 = 185984
277 + 185707 = 185984
307 + 185677 = 185984

Showing the first eight; more decompositions exist.
