Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77938, here are decompositions:
- 5 + 77933 = 77938
- 71 + 77867 = 77938
- 89 + 77849 = 77938
- 137 + 77801 = 77938
- 191 + 77747 = 77938
- 227 + 77711 = 77938
- 239 + 77699 = 77938
- 251 + 77687 = 77938
Showing the first eight; more decompositions exist.
