Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25402, here are decompositions:
- 11 + 25391 = 25402
- 29 + 25373 = 25402
- 53 + 25349 = 25402
- 59 + 25343 = 25402
- 101 + 25301 = 25402
- 149 + 25253 = 25402
- 173 + 25229 = 25402
- 233 + 25169 = 25402
Showing the first eight; more decompositions exist.
