Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178584, here are decompositions:
- 13 + 178571 = 178584
- 17 + 178567 = 178584
- 23 + 178561 = 178584
- 47 + 178537 = 178584
- 53 + 178531 = 178584
- 71 + 178513 = 178584
- 83 + 178501 = 178584
- 97 + 178487 = 178584
Showing the first eight; more decompositions exist.
