Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51984, here are decompositions:

7 + 51977 = 51984
11 + 51973 = 51984
13 + 51971 = 51984
43 + 51941 = 51984
71 + 51913 = 51984
113 + 51871 = 51984
131 + 51853 = 51984
157 + 51827 = 51984

Showing the first eight; more decompositions exist.
