Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78380, here are decompositions:

13 + 78367 = 78380
73 + 78307 = 78380
79 + 78301 = 78380
97 + 78283 = 78380
103 + 78277 = 78380
139 + 78241 = 78380
151 + 78229 = 78380
223 + 78157 = 78380

Showing the first eight; more decompositions exist.
