Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25628, here are decompositions:
- 7 + 25621 = 25628
- 19 + 25609 = 25628
- 67 + 25561 = 25628
- 157 + 25471 = 25628
- 181 + 25447 = 25628
- 271 + 25357 = 25628
- 307 + 25321 = 25628
- 367 + 25261 = 25628
Showing the first eight; more decompositions exist.
