Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3124, here are decompositions:
- 3 + 3121 = 3124
- 5 + 3119 = 3124
- 41 + 3083 = 3124
- 83 + 3041 = 3124
- 101 + 3023 = 3124
- 113 + 3011 = 3124
- 167 + 2957 = 3124
- 197 + 2927 = 3124
Showing the first eight; more decompositions exist.
