Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69142, here are decompositions:
- 23 + 69119 = 69142
- 113 + 69029 = 69142
- 131 + 69011 = 69142
- 149 + 68993 = 69142
- 179 + 68963 = 69142
- 233 + 68909 = 69142
- 239 + 68903 = 69142
- 251 + 68891 = 69142
Showing the first eight; more decompositions exist.
