Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25454, here are decompositions:
- 7 + 25447 = 25454
- 31 + 25423 = 25454
- 43 + 25411 = 25454
- 97 + 25357 = 25454
- 151 + 25303 = 25454
- 193 + 25261 = 25454
- 211 + 25243 = 25454
- 271 + 25183 = 25454
Showing the first eight; more decompositions exist.
