Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105838, here are decompositions:
- 71 + 105767 = 105838
- 137 + 105701 = 105838
- 281 + 105557 = 105838
- 311 + 105527 = 105838
- 347 + 105491 = 105838
- 389 + 105449 = 105838
- 401 + 105437 = 105838
- 431 + 105407 = 105838
Showing the first eight; more decompositions exist.
