Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17984, here are decompositions:

3 + 17981 = 17984
7 + 17977 = 17984
13 + 17971 = 17984
61 + 17923 = 17984
73 + 17911 = 17984
103 + 17881 = 17984
157 + 17827 = 17984
193 + 17791 = 17984

Showing the first eight; more decompositions exist.
