Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30582, here are decompositions:
- 5 + 30577 = 30582
- 23 + 30559 = 30582
- 29 + 30553 = 30582
- 43 + 30539 = 30582
- 53 + 30529 = 30582
- 73 + 30509 = 30582
- 89 + 30493 = 30582
- 113 + 30469 = 30582
Showing the first eight; more decompositions exist.
