Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25498, here are decompositions:
- 29 + 25469 = 25498
- 41 + 25457 = 25498
- 59 + 25439 = 25498
- 89 + 25409 = 25498
- 107 + 25391 = 25498
- 131 + 25367 = 25498
- 149 + 25349 = 25498
- 191 + 25307 = 25498
Showing the first eight; more decompositions exist.
