Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25644, here are decompositions:
- 5 + 25639 = 25644
- 11 + 25633 = 25644
- 23 + 25621 = 25644
- 41 + 25603 = 25644
- 43 + 25601 = 25644
- 61 + 25583 = 25644
- 67 + 25577 = 25644
- 83 + 25561 = 25644
Showing the first eight; more decompositions exist.
