Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163398, here are decompositions:
- 5 + 163393 = 163398
- 31 + 163367 = 163398
- 47 + 163351 = 163398
- 61 + 163337 = 163398
- 71 + 163327 = 163398
- 89 + 163309 = 163398
- 139 + 163259 = 163398
- 149 + 163249 = 163398
Showing the first eight; more decompositions exist.
