Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25188, here are decompositions:
- 5 + 25183 = 25188
- 17 + 25171 = 25188
- 19 + 25169 = 25188
- 41 + 25147 = 25188
- 61 + 25127 = 25188
- 67 + 25121 = 25188
- 71 + 25117 = 25188
- 101 + 25087 = 25188
Showing the first eight; more decompositions exist.
