Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78886, here are decompositions:

29 + 78857 = 78886
47 + 78839 = 78886
83 + 78803 = 78886
89 + 78797 = 78886
107 + 78779 = 78886
149 + 78737 = 78886
173 + 78713 = 78886
179 + 78707 = 78886

Showing the first eight; more decompositions exist.
