Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78802, here are decompositions:

5 + 78797 = 78802
11 + 78791 = 78802
23 + 78779 = 78802
89 + 78713 = 78802
149 + 78653 = 78802
179 + 78623 = 78802
233 + 78569 = 78802
263 + 78539 = 78802

Showing the first eight; more decompositions exist.
