Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021746, here are decompositions:
- 73 + 1021673 = 1021746
- 83 + 1021663 = 1021746
- 263 + 1021483 = 1021746
- 283 + 1021463 = 1021746
- 317 + 1021429 = 1021746
- 359 + 1021387 = 1021746
- 373 + 1021373 = 1021746
- 379 + 1021367 = 1021746
Showing the first eight; more decompositions exist.
