Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78658, here are decompositions:

5 + 78653 = 78658
89 + 78569 = 78658
149 + 78509 = 78658
179 + 78479 = 78658
191 + 78467 = 78658
257 + 78401 = 78658
311 + 78347 = 78658
317 + 78341 = 78658

Showing the first eight; more decompositions exist.
