Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78308, here are decompositions:

7 + 78301 = 78308
31 + 78277 = 78308
67 + 78241 = 78308
79 + 78229 = 78308
151 + 78157 = 78308
229 + 78079 = 78308
277 + 78031 = 78308
331 + 77977 = 78308

Showing the first eight; more decompositions exist.
