Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8930, here are decompositions:

7 + 8923 = 8930
37 + 8893 = 8930
43 + 8887 = 8930
67 + 8863 = 8930
109 + 8821 = 8930
127 + 8803 = 8930
151 + 8779 = 8930
193 + 8737 = 8930

Showing the first eight; more decompositions exist.
