Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2802, here are decompositions:

5 + 2797 = 2802
11 + 2791 = 2802
13 + 2789 = 2802
53 + 2749 = 2802
61 + 2741 = 2802
71 + 2731 = 2802
73 + 2729 = 2802
83 + 2719 = 2802

Showing the first eight; more decompositions exist.
