Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006866, here are decompositions:
- 5 + 1006861 = 1006866
- 13 + 1006853 = 1006866
- 19 + 1006847 = 1006866
- 67 + 1006799 = 1006866
- 83 + 1006783 = 1006866
- 97 + 1006769 = 1006866
- 127 + 1006739 = 1006866
- 229 + 1006637 = 1006866
Showing the first eight; more decompositions exist.
