Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78700, here are decompositions:

3 + 78697 = 78700
47 + 78653 = 78700
107 + 78593 = 78700
131 + 78569 = 78700
191 + 78509 = 78700
233 + 78467 = 78700
263 + 78437 = 78700
353 + 78347 = 78700

Showing the first eight; more decompositions exist.
