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.
