Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30390, here are decompositions:
- 23 + 30367 = 30390
- 43 + 30347 = 30390
- 67 + 30323 = 30390
- 71 + 30319 = 30390
- 83 + 30307 = 30390
- 97 + 30293 = 30390
- 131 + 30259 = 30390
- 137 + 30253 = 30390
Showing the first eight; more decompositions exist.
