Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105498, here are decompositions:
- 7 + 105491 = 105498
- 31 + 105467 = 105498
- 61 + 105437 = 105498
- 97 + 105401 = 105498
- 101 + 105397 = 105498
- 109 + 105389 = 105498
- 131 + 105367 = 105498
- 137 + 105361 = 105498
Showing the first eight; more decompositions exist.
