Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25424, here are decompositions:
- 13 + 25411 = 25424
- 67 + 25357 = 25424
- 103 + 25321 = 25424
- 163 + 25261 = 25424
- 181 + 25243 = 25424
- 241 + 25183 = 25424
- 271 + 25153 = 25424
- 277 + 25147 = 25424
Showing the first eight; more decompositions exist.
