Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77788, here are decompositions:
- 5 + 77783 = 77788
- 41 + 77747 = 77788
- 89 + 77699 = 77788
- 101 + 77687 = 77788
- 107 + 77681 = 77788
- 167 + 77621 = 77788
- 197 + 77591 = 77788
- 239 + 77549 = 77788
Showing the first eight; more decompositions exist.
