Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25486, here are decompositions:
- 17 + 25469 = 25486
- 23 + 25463 = 25486
- 29 + 25457 = 25486
- 47 + 25439 = 25486
- 113 + 25373 = 25486
- 137 + 25349 = 25486
- 179 + 25307 = 25486
- 233 + 25253 = 25486
Showing the first eight; more decompositions exist.
