Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25634, here are decompositions:
- 13 + 25621 = 25634
- 31 + 25603 = 25634
- 73 + 25561 = 25634
- 97 + 25537 = 25634
- 163 + 25471 = 25634
- 181 + 25453 = 25634
- 211 + 25423 = 25634
- 223 + 25411 = 25634
Showing the first eight; more decompositions exist.
