Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77216, here are decompositions:
- 3 + 77213 = 77216
- 79 + 77137 = 77216
- 193 + 77023 = 77216
- 199 + 77017 = 77216
- 379 + 76837 = 77216
- 397 + 76819 = 77216
- 439 + 76777 = 77216
- 463 + 76753 = 77216
Showing the first eight; more decompositions exist.
