Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25656, here are decompositions:
- 13 + 25643 = 25656
- 17 + 25639 = 25656
- 23 + 25633 = 25656
- 47 + 25609 = 25656
- 53 + 25603 = 25656
- 67 + 25589 = 25656
- 73 + 25583 = 25656
- 79 + 25577 = 25656
Showing the first eight; more decompositions exist.
