Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021224, here are decompositions:
- 7 + 1021217 = 1021224
- 41 + 1021183 = 1021224
- 67 + 1021157 = 1021224
- 97 + 1021127 = 1021224
- 101 + 1021123 = 1021224
- 131 + 1021093 = 1021224
- 137 + 1021087 = 1021224
- 151 + 1021073 = 1021224
Showing the first eight; more decompositions exist.
