Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8940, here are decompositions:

7 + 8933 = 8940
11 + 8929 = 8940
17 + 8923 = 8940
47 + 8893 = 8940
53 + 8887 = 8940
73 + 8867 = 8940
79 + 8861 = 8940
101 + 8839 = 8940

Showing the first eight; more decompositions exist.
