Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78310, here are decompositions:

3 + 78307 = 78310
107 + 78203 = 78310
131 + 78179 = 78310
137 + 78173 = 78310
173 + 78137 = 78310
251 + 78059 = 78310
269 + 78041 = 78310
293 + 78017 = 78310

Showing the first eight; more decompositions exist.
