Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179984, here are decompositions:

3 + 179981 = 179984
31 + 179953 = 179984
37 + 179947 = 179984
61 + 179923 = 179984
67 + 179917 = 179984
151 + 179833 = 179984
157 + 179827 = 179984
163 + 179821 = 179984

Showing the first eight; more decompositions exist.
