Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25312, here are decompositions:
- 3 + 25309 = 25312
- 5 + 25307 = 25312
- 11 + 25301 = 25312
- 59 + 25253 = 25312
- 83 + 25229 = 25312
- 149 + 25163 = 25312
- 191 + 25121 = 25312
- 239 + 25073 = 25312
Showing the first eight; more decompositions exist.
