Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30440, here are decompositions:
- 13 + 30427 = 30440
- 37 + 30403 = 30440
- 73 + 30367 = 30440
- 127 + 30313 = 30440
- 181 + 30259 = 30440
- 199 + 30241 = 30440
- 229 + 30211 = 30440
- 271 + 30169 = 30440
Showing the first eight; more decompositions exist.
