Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2824, here are decompositions:

5 + 2819 = 2824
23 + 2801 = 2824
47 + 2777 = 2824
71 + 2753 = 2824
83 + 2741 = 2824
113 + 2711 = 2824
131 + 2693 = 2824
137 + 2687 = 2824

Showing the first eight; more decompositions exist.
