Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78384, here are decompositions:
- 17 + 78367 = 78384
- 37 + 78347 = 78384
- 43 + 78341 = 78384
- 67 + 78317 = 78384
- 73 + 78311 = 78384
- 83 + 78301 = 78384
- 101 + 78283 = 78384
- 107 + 78277 = 78384
Showing the first eight; more decompositions exist.
