Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78808, here are decompositions:

5 + 78803 = 78808
11 + 78797 = 78808
17 + 78791 = 78808
29 + 78779 = 78808
71 + 78737 = 78808
101 + 78707 = 78808
239 + 78569 = 78808
269 + 78539 = 78808

Showing the first eight; more decompositions exist.
