Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028432, here are decompositions:
- 43 + 1028389 = 1028432
- 103 + 1028329 = 1028432
- 211 + 1028221 = 1028432
- 241 + 1028191 = 1028432
- 283 + 1028149 = 1028432
- 331 + 1028101 = 1028432
- 409 + 1028023 = 1028432
- 421 + 1028011 = 1028432
Showing the first eight; more decompositions exist.
