Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2224, here are decompositions:
- 3 + 2221 = 2224
- 11 + 2213 = 2224
- 17 + 2207 = 2224
- 71 + 2153 = 2224
- 83 + 2141 = 2224
- 113 + 2111 = 2224
- 137 + 2087 = 2224
- 197 + 2027 = 2224
Showing the first eight; more decompositions exist.
