Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005478, here are decompositions:
- 11 + 1005467 = 1005478
- 41 + 1005437 = 1005478
- 107 + 1005371 = 1005478
- 191 + 1005287 = 1005478
- 239 + 1005239 = 1005478
- 269 + 1005209 = 1005478
- 317 + 1005161 = 1005478
- 347 + 1005131 = 1005478
Showing the first eight; more decompositions exist.
