Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4142, here are decompositions:
- 3 + 4139 = 4142
- 13 + 4129 = 4142
- 31 + 4111 = 4142
- 43 + 4099 = 4142
- 139 + 4003 = 4142
- 199 + 3943 = 4142
- 211 + 3931 = 4142
- 223 + 3919 = 4142
Showing the first eight; more decompositions exist.
