Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2922, here are decompositions:

5 + 2917 = 2922
13 + 2909 = 2922
19 + 2903 = 2922
43 + 2879 = 2922
61 + 2861 = 2922
71 + 2851 = 2922
79 + 2843 = 2922
89 + 2833 = 2922

Showing the first eight; more decompositions exist.
