Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25200, here are decompositions:
- 11 + 25189 = 25200
- 17 + 25183 = 25200
- 29 + 25171 = 25200
- 31 + 25169 = 25200
- 37 + 25163 = 25200
- 47 + 25153 = 25200
- 53 + 25147 = 25200
- 73 + 25127 = 25200
Showing the first eight; more decompositions exist.
