Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80456, here are decompositions:
- 7 + 80449 = 80456
- 109 + 80347 = 80456
- 127 + 80329 = 80456
- 139 + 80317 = 80456
- 193 + 80263 = 80456
- 223 + 80233 = 80456
- 283 + 80173 = 80456
- 307 + 80149 = 80456
Showing the first eight; more decompositions exist.
