Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30320, here are decompositions:
- 7 + 30313 = 30320
- 13 + 30307 = 30320
- 61 + 30259 = 30320
- 67 + 30253 = 30320
- 79 + 30241 = 30320
- 97 + 30223 = 30320
- 109 + 30211 = 30320
- 139 + 30181 = 30320
Showing the first eight; more decompositions exist.
