Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3148, here are decompositions:
- 11 + 3137 = 3148
- 29 + 3119 = 3148
- 59 + 3089 = 3148
- 107 + 3041 = 3148
- 137 + 3011 = 3148
- 149 + 2999 = 3148
- 179 + 2969 = 3148
- 191 + 2957 = 3148
Showing the first eight; more decompositions exist.
