Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105388, here are decompositions:
- 29 + 105359 = 105388
- 47 + 105341 = 105388
- 137 + 105251 = 105388
- 149 + 105239 = 105388
- 251 + 105137 = 105388
- 281 + 105107 = 105388
- 317 + 105071 = 105388
- 389 + 104999 = 105388
Showing the first eight; more decompositions exist.
