Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78826, here are decompositions:

3 + 78823 = 78826
17 + 78809 = 78826
23 + 78803 = 78826
29 + 78797 = 78826
47 + 78779 = 78826
89 + 78737 = 78826
113 + 78713 = 78826
173 + 78653 = 78826

Showing the first eight; more decompositions exist.
