Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78814, here are decompositions:

5 + 78809 = 78814
11 + 78803 = 78814
17 + 78797 = 78814
23 + 78791 = 78814
101 + 78713 = 78814
107 + 78707 = 78814
191 + 78623 = 78814
317 + 78497 = 78814

Showing the first eight; more decompositions exist.
