Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4082, here are decompositions:

3 + 4079 = 4082
31 + 4051 = 4082
61 + 4021 = 4082
79 + 4003 = 4082
139 + 3943 = 4082
151 + 3931 = 4082
163 + 3919 = 4082
193 + 3889 = 4082

Showing the first eight; more decompositions exist.
