Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2898, here are decompositions:

11 + 2887 = 2898
19 + 2879 = 2898
37 + 2861 = 2898
41 + 2857 = 2898
47 + 2851 = 2898
61 + 2837 = 2898
79 + 2819 = 2898
97 + 2801 = 2898

Showing the first eight; more decompositions exist.
