Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78930, here are decompositions:

11 + 78919 = 78930
29 + 78901 = 78930
37 + 78893 = 78930
41 + 78889 = 78930
43 + 78887 = 78930
53 + 78877 = 78930
73 + 78857 = 78930
107 + 78823 = 78930

Showing the first eight; more decompositions exist.
