Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13620, here are decompositions:
- 7 + 13613 = 13620
- 23 + 13597 = 13620
- 29 + 13591 = 13620
- 43 + 13577 = 13620
- 53 + 13567 = 13620
- 67 + 13553 = 13620
- 83 + 13537 = 13620
- 97 + 13523 = 13620
Showing the first eight; more decompositions exist.
