Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7984, here are decompositions:

47 + 7937 = 7984
83 + 7901 = 7984
101 + 7883 = 7984
107 + 7877 = 7984
131 + 7853 = 7984
167 + 7817 = 7984
191 + 7793 = 7984
227 + 7757 = 7984

Showing the first eight; more decompositions exist.
