Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77756, here are decompositions:
- 13 + 77743 = 77756
- 37 + 77719 = 77756
- 43 + 77713 = 77756
- 67 + 77689 = 77756
- 97 + 77659 = 77756
- 109 + 77647 = 77756
- 139 + 77617 = 77756
- 193 + 77563 = 77756
Showing the first eight; more decompositions exist.
