Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25912, here are decompositions:
- 23 + 25889 = 25912
- 71 + 25841 = 25912
- 113 + 25799 = 25912
- 149 + 25763 = 25912
- 179 + 25733 = 25912
- 233 + 25679 = 25912
- 239 + 25673 = 25912
- 269 + 25643 = 25912
Showing the first eight; more decompositions exist.
