Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 117978, here are decompositions:

5 + 117973 = 117978
19 + 117959 = 117978
41 + 117937 = 117978
61 + 117917 = 117978
67 + 117911 = 117978
79 + 117899 = 117978
89 + 117889 = 117978
97 + 117881 = 117978

Showing the first eight; more decompositions exist.
