Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25598, here are decompositions:
- 19 + 25579 = 25598
- 37 + 25561 = 25598
- 61 + 25537 = 25598
- 127 + 25471 = 25598
- 151 + 25447 = 25598
- 241 + 25357 = 25598
- 277 + 25321 = 25598
- 337 + 25261 = 25598
Showing the first eight; more decompositions exist.
