Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021760, here are decompositions:
- 7 + 1021753 = 1021760
- 13 + 1021747 = 1021760
- 97 + 1021663 = 1021760
- 109 + 1021651 = 1021760
- 139 + 1021621 = 1021760
- 199 + 1021561 = 1021760
- 277 + 1021483 = 1021760
- 331 + 1021429 = 1021760
Showing the first eight; more decompositions exist.
