Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7930, here are decompositions:

3 + 7927 = 7930
11 + 7919 = 7930
23 + 7907 = 7930
29 + 7901 = 7930
47 + 7883 = 7930
53 + 7877 = 7930
89 + 7841 = 7930
101 + 7829 = 7930

Showing the first eight; more decompositions exist.
