Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30660, here are decompositions:
- 11 + 30649 = 30660
- 17 + 30643 = 30660
- 23 + 30637 = 30660
- 29 + 30631 = 30660
- 67 + 30593 = 30660
- 83 + 30577 = 30660
- 101 + 30559 = 30660
- 103 + 30557 = 30660
Showing the first eight; more decompositions exist.
