Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51748, here are decompositions:
- 29 + 51719 = 51748
- 89 + 51659 = 51748
- 101 + 51647 = 51748
- 149 + 51599 = 51748
- 167 + 51581 = 51748
- 197 + 51551 = 51748
- 227 + 51521 = 51748
- 269 + 51479 = 51748
Showing the first eight; more decompositions exist.
