Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25198, here are decompositions:
- 29 + 25169 = 25198
- 71 + 25127 = 25198
- 101 + 25097 = 25198
- 167 + 25031 = 25198
- 227 + 24971 = 25198
- 281 + 24917 = 25198
- 347 + 24851 = 25198
- 389 + 24809 = 25198
Showing the first eight; more decompositions exist.
