Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028564, here are decompositions:
- 3 + 1028561 = 1028564
- 7 + 1028557 = 1028564
- 127 + 1028437 = 1028564
- 373 + 1028191 = 1028564
- 457 + 1028107 = 1028564
- 463 + 1028101 = 1028564
- 541 + 1028023 = 1028564
- 547 + 1028017 = 1028564
Showing the first eight; more decompositions exist.
