Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3208, here are decompositions:
- 5 + 3203 = 3208
- 17 + 3191 = 3208
- 41 + 3167 = 3208
- 71 + 3137 = 3208
- 89 + 3119 = 3208
- 167 + 3041 = 3208
- 197 + 3011 = 3208
- 239 + 2969 = 3208
Showing the first eight; more decompositions exist.
