Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25662, here are decompositions:
- 5 + 25657 = 25662
- 19 + 25643 = 25662
- 23 + 25639 = 25662
- 29 + 25633 = 25662
- 41 + 25621 = 25662
- 53 + 25609 = 25662
- 59 + 25603 = 25662
- 61 + 25601 = 25662
Showing the first eight; more decompositions exist.
