Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6780, here are decompositions:
- 17 + 6763 = 6780
- 19 + 6761 = 6780
- 43 + 6737 = 6780
- 47 + 6733 = 6780
- 61 + 6719 = 6780
- 71 + 6709 = 6780
- 79 + 6701 = 6780
- 89 + 6691 = 6780
Showing the first eight; more decompositions exist.
