Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30458, here are decompositions:
- 31 + 30427 = 30458
- 67 + 30391 = 30458
- 139 + 30319 = 30458
- 151 + 30307 = 30458
- 199 + 30259 = 30458
- 271 + 30187 = 30458
- 277 + 30181 = 30458
- 349 + 30109 = 30458
Showing the first eight; more decompositions exist.
