Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78122, here are decompositions:
- 43 + 78079 = 78122
- 73 + 78049 = 78122
- 139 + 77983 = 78122
- 193 + 77929 = 78122
- 223 + 77899 = 78122
- 229 + 77893 = 78122
- 283 + 77839 = 78122
- 349 + 77773 = 78122
Showing the first eight; more decompositions exist.
