Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178224, here are decompositions:
- 17 + 178207 = 178224
- 37 + 178187 = 178224
- 41 + 178183 = 178224
- 73 + 178151 = 178224
- 83 + 178141 = 178224
- 97 + 178127 = 178224
- 107 + 178117 = 178224
- 131 + 178093 = 178224
Showing the first eight; more decompositions exist.
