Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25482, here are decompositions:
- 11 + 25471 = 25482
- 13 + 25469 = 25482
- 19 + 25463 = 25482
- 29 + 25453 = 25482
- 43 + 25439 = 25482
- 59 + 25423 = 25482
- 71 + 25411 = 25482
- 73 + 25409 = 25482
Showing the first eight; more decompositions exist.
