Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8946, here are decompositions:

5 + 8941 = 8946
13 + 8933 = 8946
17 + 8929 = 8946
23 + 8923 = 8946
53 + 8893 = 8946
59 + 8887 = 8946
79 + 8867 = 8946
83 + 8863 = 8946

Showing the first eight; more decompositions exist.
