Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4216, here are decompositions:
- 5 + 4211 = 4216
- 59 + 4157 = 4216
- 83 + 4133 = 4216
- 89 + 4127 = 4216
- 137 + 4079 = 4216
- 167 + 4049 = 4216
- 197 + 4019 = 4216
- 227 + 3989 = 4216
Showing the first eight; more decompositions exist.
