Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7766, here are decompositions:
- 7 + 7759 = 7766
- 13 + 7753 = 7766
- 43 + 7723 = 7766
- 67 + 7699 = 7766
- 79 + 7687 = 7766
- 97 + 7669 = 7766
- 127 + 7639 = 7766
- 163 + 7603 = 7766
Showing the first eight; more decompositions exist.
