Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163388, here are decompositions:
- 37 + 163351 = 163388
- 61 + 163327 = 163388
- 67 + 163321 = 163388
- 79 + 163309 = 163388
- 139 + 163249 = 163388
- 241 + 163147 = 163388
- 271 + 163117 = 163388
- 367 + 163021 = 163388
Showing the first eight; more decompositions exist.
