Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25558, here are decompositions:
- 17 + 25541 = 25558
- 89 + 25469 = 25558
- 101 + 25457 = 25558
- 149 + 25409 = 25558
- 167 + 25391 = 25558
- 191 + 25367 = 25558
- 251 + 25307 = 25558
- 257 + 25301 = 25558
Showing the first eight; more decompositions exist.
