Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021706, here are decompositions:
- 43 + 1021663 = 1021706
- 79 + 1021627 = 1021706
- 223 + 1021483 = 1021706
- 277 + 1021429 = 1021706
- 337 + 1021369 = 1021706
- 373 + 1021333 = 1021706
- 379 + 1021327 = 1021706
- 409 + 1021297 = 1021706
Showing the first eight; more decompositions exist.
