Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30584, here are decompositions:
- 7 + 30577 = 30584
- 31 + 30553 = 30584
- 67 + 30517 = 30584
- 157 + 30427 = 30584
- 181 + 30403 = 30584
- 193 + 30391 = 30584
- 271 + 30313 = 30584
- 277 + 30307 = 30584
Showing the first eight; more decompositions exist.
