Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25512, here are decompositions:
- 41 + 25471 = 25512
- 43 + 25469 = 25512
- 59 + 25453 = 25512
- 73 + 25439 = 25512
- 89 + 25423 = 25512
- 101 + 25411 = 25512
- 103 + 25409 = 25512
- 139 + 25373 = 25512
Showing the first eight; more decompositions exist.
