Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25568, here are decompositions:
- 7 + 25561 = 25568
- 31 + 25537 = 25568
- 97 + 25471 = 25568
- 157 + 25411 = 25568
- 211 + 25357 = 25568
- 229 + 25339 = 25568
- 307 + 25261 = 25568
- 331 + 25237 = 25568
Showing the first eight; more decompositions exist.
