Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548736, here are decompositions:
- 3 + 31548733 = 31548736
- 59 + 31548677 = 31548736
- 83 + 31548653 = 31548736
- 173 + 31548563 = 31548736
- 269 + 31548467 = 31548736
- 293 + 31548443 = 31548736
- 449 + 31548287 = 31548736
- 467 + 31548269 = 31548736
Showing the first eight; more decompositions exist.
