Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25488, here are decompositions:
- 17 + 25471 = 25488
- 19 + 25469 = 25488
- 31 + 25457 = 25488
- 41 + 25447 = 25488
- 79 + 25409 = 25488
- 97 + 25391 = 25488
- 131 + 25357 = 25488
- 139 + 25349 = 25488
Showing the first eight; more decompositions exist.
