Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25360, here are decompositions:
- 3 + 25357 = 25360
- 11 + 25349 = 25360
- 17 + 25343 = 25360
- 53 + 25307 = 25360
- 59 + 25301 = 25360
- 107 + 25253 = 25360
- 113 + 25247 = 25360
- 131 + 25229 = 25360
Showing the first eight; more decompositions exist.
