Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3200, here are decompositions:
- 13 + 3187 = 3200
- 19 + 3181 = 3200
- 31 + 3169 = 3200
- 37 + 3163 = 3200
- 79 + 3121 = 3200
- 139 + 3061 = 3200
- 151 + 3049 = 3200
- 163 + 3037 = 3200
Showing the first eight; more decompositions exist.
