Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3992, here are decompositions:

3 + 3989 = 3992
61 + 3931 = 3992
73 + 3919 = 3992
103 + 3889 = 3992
139 + 3853 = 3992
199 + 3793 = 3992
223 + 3769 = 3992
283 + 3709 = 3992

Showing the first eight; more decompositions exist.
