Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25618, here are decompositions:
- 17 + 25601 = 25618
- 29 + 25589 = 25618
- 41 + 25577 = 25618
- 149 + 25469 = 25618
- 179 + 25439 = 25618
- 227 + 25391 = 25618
- 251 + 25367 = 25618
- 269 + 25349 = 25618
Showing the first eight; more decompositions exist.
