Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25786, here are decompositions:
- 23 + 25763 = 25786
- 53 + 25733 = 25786
- 83 + 25703 = 25786
- 107 + 25679 = 25786
- 113 + 25673 = 25786
- 197 + 25589 = 25786
- 263 + 25523 = 25786
- 317 + 25469 = 25786
Showing the first eight; more decompositions exist.
