Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4224, here are decompositions:
- 5 + 4219 = 4224
- 7 + 4217 = 4224
- 13 + 4211 = 4224
- 23 + 4201 = 4224
- 47 + 4177 = 4224
- 67 + 4157 = 4224
- 71 + 4153 = 4224
- 97 + 4127 = 4224
Showing the first eight; more decompositions exist.
