Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005906, here are decompositions:
- 23 + 1005883 = 1005906
- 73 + 1005833 = 1005906
- 79 + 1005827 = 1005906
- 197 + 1005709 = 1005906
- 227 + 1005679 = 1005906
- 229 + 1005677 = 1005906
- 263 + 1005643 = 1005906
- 269 + 1005637 = 1005906
Showing the first eight; more decompositions exist.
