Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25538, here are decompositions:
- 67 + 25471 = 25538
- 127 + 25411 = 25538
- 181 + 25357 = 25538
- 199 + 25339 = 25538
- 229 + 25309 = 25538
- 277 + 25261 = 25538
- 349 + 25189 = 25538
- 367 + 25171 = 25538
Showing the first eight; more decompositions exist.
