Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6930, here are decompositions:

13 + 6917 = 6930
19 + 6911 = 6930
23 + 6907 = 6930
31 + 6899 = 6930
47 + 6883 = 6930
59 + 6871 = 6930
61 + 6869 = 6930
67 + 6863 = 6930

Showing the first eight; more decompositions exist.
