Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178750, here are decompositions:
- 53 + 178697 = 178750
- 59 + 178691 = 178750
- 107 + 178643 = 178750
- 137 + 178613 = 178750
- 149 + 178601 = 178750
- 179 + 178571 = 178750
- 191 + 178559 = 178750
- 263 + 178487 = 178750
Showing the first eight; more decompositions exist.
