Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30330, here are decompositions:
- 7 + 30323 = 30330
- 11 + 30319 = 30330
- 17 + 30313 = 30330
- 23 + 30307 = 30330
- 37 + 30293 = 30330
- 59 + 30271 = 30330
- 61 + 30269 = 30330
- 71 + 30259 = 30330
Showing the first eight; more decompositions exist.
