Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7782, here are decompositions:
- 23 + 7759 = 7782
- 29 + 7753 = 7782
- 41 + 7741 = 7782
- 59 + 7723 = 7782
- 79 + 7703 = 7782
- 83 + 7699 = 7782
- 101 + 7681 = 7782
- 109 + 7673 = 7782
Showing the first eight; more decompositions exist.
