Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18468, here are decompositions:
- 7 + 18461 = 18468
- 11 + 18457 = 18468
- 17 + 18451 = 18468
- 29 + 18439 = 18468
- 41 + 18427 = 18468
- 67 + 18401 = 18468
- 71 + 18397 = 18468
- 89 + 18379 = 18468
Showing the first eight; more decompositions exist.
