Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78338, here are decompositions:

31 + 78307 = 78338
37 + 78301 = 78338
61 + 78277 = 78338
79 + 78259 = 78338
97 + 78241 = 78338
109 + 78229 = 78338
181 + 78157 = 78338
199 + 78139 = 78338

Showing the first eight; more decompositions exist.
