Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2884, here are decompositions:

5 + 2879 = 2884
23 + 2861 = 2884
41 + 2843 = 2884
47 + 2837 = 2884
83 + 2801 = 2884
107 + 2777 = 2884
131 + 2753 = 2884
173 + 2711 = 2884

Showing the first eight; more decompositions exist.
