Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30380, here are decompositions:
- 13 + 30367 = 30380
- 61 + 30319 = 30380
- 67 + 30313 = 30380
- 73 + 30307 = 30380
- 109 + 30271 = 30380
- 127 + 30253 = 30380
- 139 + 30241 = 30380
- 157 + 30223 = 30380
Showing the first eight; more decompositions exist.
