Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77824, here are decompositions:
- 11 + 77813 = 77824
- 23 + 77801 = 77824
- 41 + 77783 = 77824
- 101 + 77723 = 77824
- 113 + 77711 = 77824
- 137 + 77687 = 77824
- 233 + 77591 = 77824
- 251 + 77573 = 77824
Showing the first eight; more decompositions exist.
