Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542306, here are decompositions:
- 73 + 31542233 = 31542306
- 109 + 31542197 = 31542306
- 157 + 31542149 = 31542306
- 193 + 31542113 = 31542306
- 223 + 31542083 = 31542306
- 239 + 31542067 = 31542306
- 269 + 31542037 = 31542306
- 283 + 31542023 = 31542306
Showing the first eight; more decompositions exist.
