Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2900, here are decompositions:

3 + 2897 = 2900
13 + 2887 = 2900
43 + 2857 = 2900
67 + 2833 = 2900
97 + 2803 = 2900
103 + 2797 = 2900
109 + 2791 = 2900
151 + 2749 = 2900

Showing the first eight; more decompositions exist.
