Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25480, here are decompositions:
- 11 + 25469 = 25480
- 17 + 25463 = 25480
- 23 + 25457 = 25480
- 41 + 25439 = 25480
- 71 + 25409 = 25480
- 89 + 25391 = 25480
- 107 + 25373 = 25480
- 113 + 25367 = 25480
Showing the first eight; more decompositions exist.
