Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021832, here are decompositions:
- 73 + 1021759 = 1021832
- 79 + 1021753 = 1021832
- 181 + 1021651 = 1021832
- 211 + 1021621 = 1021832
- 271 + 1021561 = 1021832
- 349 + 1021483 = 1021832
- 463 + 1021369 = 1021832
- 499 + 1021333 = 1021832
Showing the first eight; more decompositions exist.
