Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2882, here are decompositions:

3 + 2879 = 2882
31 + 2851 = 2882
79 + 2803 = 2882
151 + 2731 = 2882
163 + 2719 = 2882
193 + 2689 = 2882
199 + 2683 = 2882
211 + 2671 = 2882

Showing the first eight; more decompositions exist.
