Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78464, here are decompositions:

37 + 78427 = 78464
97 + 78367 = 78464
157 + 78307 = 78464
163 + 78301 = 78464
181 + 78283 = 78464
223 + 78241 = 78464
271 + 78193 = 78464
307 + 78157 = 78464

Showing the first eight; more decompositions exist.
