Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7224, here are decompositions:
- 5 + 7219 = 7224
- 11 + 7213 = 7224
- 13 + 7211 = 7224
- 17 + 7207 = 7224
- 31 + 7193 = 7224
- 37 + 7187 = 7224
- 47 + 7177 = 7224
- 73 + 7151 = 7224
Showing the first eight; more decompositions exist.
