Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78868, here are decompositions:

11 + 78857 = 78868
29 + 78839 = 78868
59 + 78809 = 78868
71 + 78797 = 78868
89 + 78779 = 78868
131 + 78737 = 78868
359 + 78509 = 78868
389 + 78479 = 78868

Showing the first eight; more decompositions exist.
