Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30480, here are decompositions:
- 11 + 30469 = 30480
- 13 + 30467 = 30480
- 31 + 30449 = 30480
- 53 + 30427 = 30480
- 89 + 30391 = 30480
- 113 + 30367 = 30480
- 139 + 30341 = 30480
- 157 + 30323 = 30480
Showing the first eight; more decompositions exist.
