Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51724, here are decompositions:
- 3 + 51721 = 51724
- 5 + 51719 = 51724
- 11 + 51713 = 51724
- 41 + 51683 = 51724
- 131 + 51593 = 51724
- 173 + 51551 = 51724
- 251 + 51473 = 51724
- 263 + 51461 = 51724
Showing the first eight; more decompositions exist.
