Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25318, here are decompositions:
- 11 + 25307 = 25318
- 17 + 25301 = 25318
- 71 + 25247 = 25318
- 89 + 25229 = 25318
- 149 + 25169 = 25318
- 191 + 25127 = 25318
- 197 + 25121 = 25318
- 281 + 25037 = 25318
Showing the first eight; more decompositions exist.
