Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25258, here are decompositions:
- 5 + 25253 = 25258
- 11 + 25247 = 25258
- 29 + 25229 = 25258
- 89 + 25169 = 25258
- 131 + 25127 = 25258
- 137 + 25121 = 25258
- 227 + 25031 = 25258
- 269 + 24989 = 25258
Showing the first eight; more decompositions exist.
