Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4122, here are decompositions:
- 11 + 4111 = 4122
- 23 + 4099 = 4122
- 29 + 4093 = 4122
- 31 + 4091 = 4122
- 43 + 4079 = 4122
- 71 + 4051 = 4122
- 73 + 4049 = 4122
- 101 + 4021 = 4122
Showing the first eight; more decompositions exist.
