Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12620, here are decompositions:
- 7 + 12613 = 12620
- 19 + 12601 = 12620
- 31 + 12589 = 12620
- 37 + 12583 = 12620
- 43 + 12577 = 12620
- 67 + 12553 = 12620
- 73 + 12547 = 12620
- 79 + 12541 = 12620
Showing the first eight; more decompositions exist.
