Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77890, here are decompositions:
- 23 + 77867 = 77890
- 41 + 77849 = 77890
- 89 + 77801 = 77890
- 107 + 77783 = 77890
- 167 + 77723 = 77890
- 179 + 77711 = 77890
- 191 + 77699 = 77890
- 269 + 77621 = 77890
Showing the first eight; more decompositions exist.
