Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78828, here are decompositions:

5 + 78823 = 78828
19 + 78809 = 78828
31 + 78797 = 78828
37 + 78791 = 78828
41 + 78787 = 78828
47 + 78781 = 78828
107 + 78721 = 78828
131 + 78697 = 78828

Showing the first eight; more decompositions exist.
