Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77782, here are decompositions:
- 59 + 77723 = 77782
- 71 + 77711 = 77782
- 83 + 77699 = 77782
- 101 + 77681 = 77782
- 191 + 77591 = 77782
- 233 + 77549 = 77782
- 239 + 77543 = 77782
- 269 + 77513 = 77782
Showing the first eight; more decompositions exist.
