Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78858, here are decompositions:

5 + 78853 = 78858
19 + 78839 = 78858
61 + 78797 = 78858
67 + 78791 = 78858
71 + 78787 = 78858
79 + 78779 = 78858
137 + 78721 = 78858
151 + 78707 = 78858

Showing the first eight; more decompositions exist.
