Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25718, here are decompositions:
- 61 + 25657 = 25718
- 79 + 25639 = 25718
- 97 + 25621 = 25718
- 109 + 25609 = 25718
- 139 + 25579 = 25718
- 157 + 25561 = 25718
- 181 + 25537 = 25718
- 271 + 25447 = 25718
Showing the first eight; more decompositions exist.
