Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3212, here are decompositions:
- 3 + 3209 = 3212
- 31 + 3181 = 3212
- 43 + 3169 = 3212
- 103 + 3109 = 3212
- 151 + 3061 = 3212
- 163 + 3049 = 3212
- 193 + 3019 = 3212
- 211 + 3001 = 3212
Showing the first eight; more decompositions exist.
