Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10122, here are decompositions:
- 11 + 10111 = 10122
- 19 + 10103 = 10122
- 23 + 10099 = 10122
- 29 + 10093 = 10122
- 31 + 10091 = 10122
- 43 + 10079 = 10122
- 53 + 10069 = 10122
- 61 + 10061 = 10122
Showing the first eight; more decompositions exist.
