Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012720, here are decompositions:
- 3 + 1012717 = 1012720
- 17 + 1012703 = 1012720
- 29 + 1012691 = 1012720
- 41 + 1012679 = 1012720
- 83 + 1012637 = 1012720
- 89 + 1012631 = 1012720
- 101 + 1012619 = 1012720
- 173 + 1012547 = 1012720
Showing the first eight; more decompositions exist.
