Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25586, here are decompositions:
- 3 + 25583 = 25586
- 7 + 25579 = 25586
- 139 + 25447 = 25586
- 163 + 25423 = 25586
- 229 + 25357 = 25586
- 277 + 25309 = 25586
- 283 + 25303 = 25586
- 349 + 25237 = 25586
Showing the first eight; more decompositions exist.
