Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73224, here are decompositions:
- 43 + 73181 = 73224
- 83 + 73141 = 73224
- 97 + 73127 = 73224
- 103 + 73121 = 73224
- 163 + 73061 = 73224
- 181 + 73043 = 73224
- 211 + 73013 = 73224
- 227 + 72997 = 73224
Showing the first eight; more decompositions exist.
