Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77992, here are decompositions:
- 23 + 77969 = 77992
- 41 + 77951 = 77992
- 59 + 77933 = 77992
- 179 + 77813 = 77992
- 191 + 77801 = 77992
- 269 + 77723 = 77992
- 281 + 77711 = 77992
- 293 + 77699 = 77992
Showing the first eight; more decompositions exist.
