Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25492, here are decompositions:
- 23 + 25469 = 25492
- 29 + 25463 = 25492
- 53 + 25439 = 25492
- 83 + 25409 = 25492
- 101 + 25391 = 25492
- 149 + 25343 = 25492
- 191 + 25301 = 25492
- 239 + 25253 = 25492
Showing the first eight; more decompositions exist.
