Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25180, here are decompositions:
- 11 + 25169 = 25180
- 17 + 25163 = 25180
- 53 + 25127 = 25180
- 59 + 25121 = 25180
- 83 + 25097 = 25180
- 107 + 25073 = 25180
- 149 + 25031 = 25180
- 167 + 25013 = 25180
Showing the first eight; more decompositions exist.
