Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77818, here are decompositions:
- 5 + 77813 = 77818
- 17 + 77801 = 77818
- 71 + 77747 = 77818
- 107 + 77711 = 77818
- 131 + 77687 = 77818
- 137 + 77681 = 77818
- 197 + 77621 = 77818
- 227 + 77591 = 77818
Showing the first eight; more decompositions exist.
