Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78512, here are decompositions:

3 + 78509 = 78512
73 + 78439 = 78512
211 + 78301 = 78512
229 + 78283 = 78512
271 + 78241 = 78512
283 + 78229 = 78512
349 + 78163 = 78512
373 + 78139 = 78512

Showing the first eight; more decompositions exist.
