Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006740, here are decompositions:
- 19 + 1006721 = 1006740
- 29 + 1006711 = 1006740
- 89 + 1006651 = 1006740
- 103 + 1006637 = 1006740
- 107 + 1006633 = 1006740
- 127 + 1006613 = 1006740
- 131 + 1006609 = 1006740
- 151 + 1006589 = 1006740
Showing the first eight; more decompositions exist.
