Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25450, here are decompositions:
- 3 + 25447 = 25450
- 11 + 25439 = 25450
- 41 + 25409 = 25450
- 59 + 25391 = 25450
- 83 + 25367 = 25450
- 101 + 25349 = 25450
- 107 + 25343 = 25450
- 149 + 25301 = 25450
Showing the first eight; more decompositions exist.
