Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159224, here are decompositions:
- 31 + 159193 = 159224
- 67 + 159157 = 159224
- 127 + 159097 = 159224
- 151 + 159073 = 159224
- 211 + 159013 = 159224
- 283 + 158941 = 159224
- 421 + 158803 = 159224
- 433 + 158791 = 159224
Showing the first eight; more decompositions exist.
