Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3142, here are decompositions:
- 5 + 3137 = 3142
- 23 + 3119 = 3142
- 53 + 3089 = 3142
- 59 + 3083 = 3142
- 101 + 3041 = 3142
- 131 + 3011 = 3142
- 173 + 2969 = 3142
- 179 + 2963 = 3142
Showing the first eight; more decompositions exist.
