Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78340, here are decompositions:

23 + 78317 = 78340
29 + 78311 = 78340
107 + 78233 = 78340
137 + 78203 = 78340
149 + 78191 = 78340
167 + 78173 = 78340
173 + 78167 = 78340
239 + 78101 = 78340

Showing the first eight; more decompositions exist.
