Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39984, here are decompositions:

5 + 39979 = 39984
13 + 39971 = 39984
31 + 39953 = 39984
47 + 39937 = 39984
83 + 39901 = 39984
97 + 39887 = 39984
101 + 39883 = 39984
107 + 39877 = 39984

Showing the first eight; more decompositions exist.
