Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3256, here are decompositions:
- 3 + 3253 = 3256
- 5 + 3251 = 3256
- 47 + 3209 = 3256
- 53 + 3203 = 3256
- 89 + 3167 = 3256
- 137 + 3119 = 3256
- 167 + 3089 = 3256
- 173 + 3083 = 3256
Showing the first eight; more decompositions exist.
