Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021080, here are decompositions:
- 7 + 1021073 = 1021080
- 13 + 1021067 = 1021080
- 37 + 1021043 = 1021080
- 61 + 1021019 = 1021080
- 79 + 1021001 = 1021080
- 83 + 1020997 = 1021080
- 89 + 1020991 = 1021080
- 101 + 1020979 = 1021080
Showing the first eight; more decompositions exist.
