Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25390, here are decompositions:
- 17 + 25373 = 25390
- 23 + 25367 = 25390
- 41 + 25349 = 25390
- 47 + 25343 = 25390
- 83 + 25307 = 25390
- 89 + 25301 = 25390
- 137 + 25253 = 25390
- 227 + 25163 = 25390
Showing the first eight; more decompositions exist.
