Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25684, here are decompositions:
- 5 + 25679 = 25684
- 11 + 25673 = 25684
- 17 + 25667 = 25684
- 41 + 25643 = 25684
- 83 + 25601 = 25684
- 101 + 25583 = 25684
- 107 + 25577 = 25684
- 227 + 25457 = 25684
Showing the first eight; more decompositions exist.
