Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111984, here are decompositions:

7 + 111977 = 111984
11 + 111973 = 111984
31 + 111953 = 111984
71 + 111913 = 111984
113 + 111871 = 111984
127 + 111857 = 111984
137 + 111847 = 111984
151 + 111833 = 111984

Showing the first eight; more decompositions exist.
