Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056720, here are decompositions:
- 13 + 1056707 = 1056720
- 53 + 1056667 = 1056720
- 61 + 1056659 = 1056720
- 79 + 1056641 = 1056720
- 97 + 1056623 = 1056720
- 103 + 1056617 = 1056720
- 107 + 1056613 = 1056720
- 131 + 1056589 = 1056720
Showing the first eight; more decompositions exist.
