Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20122, here are decompositions:
- 5 + 20117 = 20122
- 59 + 20063 = 20122
- 71 + 20051 = 20122
- 101 + 20021 = 20122
- 131 + 19991 = 20122
- 149 + 19973 = 20122
- 173 + 19949 = 20122
- 233 + 19889 = 20122
Showing the first eight; more decompositions exist.
