Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4112, here are decompositions:
- 13 + 4099 = 4112
- 19 + 4093 = 4112
- 61 + 4051 = 4112
- 109 + 4003 = 4112
- 181 + 3931 = 4112
- 193 + 3919 = 4112
- 223 + 3889 = 4112
- 373 + 3739 = 4112
Showing the first eight; more decompositions exist.
