Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25646, here are decompositions:
- 3 + 25643 = 25646
- 7 + 25639 = 25646
- 13 + 25633 = 25646
- 37 + 25609 = 25646
- 43 + 25603 = 25646
- 67 + 25579 = 25646
- 109 + 25537 = 25646
- 193 + 25453 = 25646
Showing the first eight; more decompositions exist.
