Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25320, here are decompositions:
- 11 + 25309 = 25320
- 13 + 25307 = 25320
- 17 + 25303 = 25320
- 19 + 25301 = 25320
- 59 + 25261 = 25320
- 67 + 25253 = 25320
- 73 + 25247 = 25320
- 83 + 25237 = 25320
Showing the first eight; more decompositions exist.
