Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78216, here are decompositions:

13 + 78203 = 78216
23 + 78193 = 78216
37 + 78179 = 78216
43 + 78173 = 78216
53 + 78163 = 78216
59 + 78157 = 78216
79 + 78137 = 78216
137 + 78079 = 78216

Showing the first eight; more decompositions exist.
