Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22122, here are decompositions:
- 11 + 22111 = 22122
- 13 + 22109 = 22122
- 29 + 22093 = 22122
- 31 + 22091 = 22122
- 43 + 22079 = 22122
- 59 + 22063 = 22122
- 71 + 22051 = 22122
- 83 + 22039 = 22122
Showing the first eight; more decompositions exist.
