Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78768, here are decompositions:

31 + 78737 = 78768
47 + 78721 = 78768
61 + 78707 = 78768
71 + 78697 = 78768
191 + 78577 = 78768
197 + 78571 = 78768
199 + 78569 = 78768
227 + 78541 = 78768

Showing the first eight; more decompositions exist.
