Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78290, here are decompositions:

7 + 78283 = 78290
13 + 78277 = 78290
31 + 78259 = 78290
61 + 78229 = 78290
97 + 78193 = 78290
127 + 78163 = 78290
151 + 78139 = 78290
211 + 78079 = 78290

Showing the first eight; more decompositions exist.
