Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25456, here are decompositions:
- 3 + 25453 = 25456
- 17 + 25439 = 25456
- 47 + 25409 = 25456
- 83 + 25373 = 25456
- 89 + 25367 = 25456
- 107 + 25349 = 25456
- 113 + 25343 = 25456
- 149 + 25307 = 25456
Showing the first eight; more decompositions exist.
