Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64216, here are decompositions:
- 29 + 64187 = 64216
- 59 + 64157 = 64216
- 107 + 64109 = 64216
- 149 + 64067 = 64216
- 179 + 64037 = 64216
- 197 + 64019 = 64216
- 239 + 63977 = 64216
- 353 + 63863 = 64216
Showing the first eight; more decompositions exist.
