Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2876, here are decompositions:

19 + 2857 = 2876
43 + 2833 = 2876
73 + 2803 = 2876
79 + 2797 = 2876
109 + 2767 = 2876
127 + 2749 = 2876
157 + 2719 = 2876
163 + 2713 = 2876

Showing the first eight; more decompositions exist.
