Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022730, here are decompositions:
- 11 + 1022719 = 1022730
- 29 + 1022701 = 1022730
- 41 + 1022689 = 1022730
- 47 + 1022683 = 1022730
- 53 + 1022677 = 1022730
- 97 + 1022633 = 1022730
- 101 + 1022629 = 1022730
- 139 + 1022591 = 1022730
Showing the first eight; more decompositions exist.
