Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78918, here are decompositions:

17 + 78901 = 78918
29 + 78889 = 78918
31 + 78887 = 78918
41 + 78877 = 78918
61 + 78857 = 78918
79 + 78839 = 78918
109 + 78809 = 78918
127 + 78791 = 78918

Showing the first eight; more decompositions exist.
