Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022868, here are decompositions:
- 19 + 1022849 = 1022868
- 31 + 1022837 = 1022868
- 47 + 1022821 = 1022868
- 71 + 1022797 = 1022868
- 107 + 1022761 = 1022868
- 139 + 1022729 = 1022868
- 149 + 1022719 = 1022868
- 167 + 1022701 = 1022868
Showing the first eight; more decompositions exist.
