Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2848, here are decompositions:

5 + 2843 = 2848
11 + 2837 = 2848
29 + 2819 = 2848
47 + 2801 = 2848
59 + 2789 = 2848
71 + 2777 = 2848
107 + 2741 = 2848
137 + 2711 = 2848

Showing the first eight; more decompositions exist.
