Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2862, here are decompositions:

5 + 2857 = 2862
11 + 2851 = 2862
19 + 2843 = 2862
29 + 2833 = 2862
43 + 2819 = 2862
59 + 2803 = 2862
61 + 2801 = 2862
71 + 2791 = 2862

Showing the first eight; more decompositions exist.
