Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25500, here are decompositions:
- 29 + 25471 = 25500
- 31 + 25469 = 25500
- 37 + 25463 = 25500
- 43 + 25457 = 25500
- 47 + 25453 = 25500
- 53 + 25447 = 25500
- 61 + 25439 = 25500
- 89 + 25411 = 25500
Showing the first eight; more decompositions exist.
