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.
