Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25906, here are decompositions:
- 3 + 25903 = 25906
- 17 + 25889 = 25906
- 59 + 25847 = 25906
- 107 + 25799 = 25906
- 113 + 25793 = 25906
- 173 + 25733 = 25906
- 227 + 25679 = 25906
- 233 + 25673 = 25906
Showing the first eight; more decompositions exist.
