Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13930, here are decompositions:

17 + 13913 = 13930
23 + 13907 = 13930
29 + 13901 = 13930
47 + 13883 = 13930
53 + 13877 = 13930
71 + 13859 = 13930
89 + 13841 = 13930
101 + 13829 = 13930

Showing the first eight; more decompositions exist.
