Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30620, here are decompositions:
- 43 + 30577 = 30620
- 61 + 30559 = 30620
- 67 + 30553 = 30620
- 103 + 30517 = 30620
- 127 + 30493 = 30620
- 151 + 30469 = 30620
- 193 + 30427 = 30620
- 229 + 30391 = 30620
Showing the first eight; more decompositions exist.
