Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78404, here are decompositions:

3 + 78401 = 78404
37 + 78367 = 78404
97 + 78307 = 78404
103 + 78301 = 78404
127 + 78277 = 78404
163 + 78241 = 78404
211 + 78193 = 78404
241 + 78163 = 78404

Showing the first eight; more decompositions exist.
