Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77858, here are decompositions:

19 + 77839 = 77858
61 + 77797 = 77858
97 + 77761 = 77858
127 + 77731 = 77858
139 + 77719 = 77858
199 + 77659 = 77858
211 + 77647 = 77858
241 + 77617 = 77858

Showing the first eight; more decompositions exist.
