Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77666, here are decompositions:
- 7 + 77659 = 77666
- 19 + 77647 = 77666
- 79 + 77587 = 77666
- 97 + 77569 = 77666
- 103 + 77563 = 77666
- 109 + 77557 = 77666
- 139 + 77527 = 77666
- 157 + 77509 = 77666
Showing the first eight; more decompositions exist.
