Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25356, here are decompositions:
- 7 + 25349 = 25356
- 13 + 25343 = 25356
- 17 + 25339 = 25356
- 47 + 25309 = 25356
- 53 + 25303 = 25356
- 103 + 25253 = 25356
- 109 + 25247 = 25356
- 113 + 25243 = 25356
Showing the first eight; more decompositions exist.
