Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77878, here are decompositions:
- 11 + 77867 = 77878
- 29 + 77849 = 77878
- 131 + 77747 = 77878
- 167 + 77711 = 77878
- 179 + 77699 = 77878
- 191 + 77687 = 77878
- 197 + 77681 = 77878
- 257 + 77621 = 77878
Showing the first eight; more decompositions exist.
