Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25018, here are decompositions:
- 5 + 25013 = 25018
- 29 + 24989 = 25018
- 41 + 24977 = 25018
- 47 + 24971 = 25018
- 101 + 24917 = 25018
- 167 + 24851 = 25018
- 197 + 24821 = 25018
- 251 + 24767 = 25018
Showing the first eight; more decompositions exist.
