Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12630, here are decompositions:
- 11 + 12619 = 12630
- 17 + 12613 = 12630
- 19 + 12611 = 12630
- 29 + 12601 = 12630
- 41 + 12589 = 12630
- 47 + 12583 = 12630
- 53 + 12577 = 12630
- 61 + 12569 = 12630
Showing the first eight; more decompositions exist.
