Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105188, here are decompositions:
- 151 + 105037 = 105188
- 157 + 105031 = 105188
- 229 + 104959 = 105188
- 241 + 104947 = 105188
- 271 + 104917 = 105188
- 277 + 104911 = 105188
- 337 + 104851 = 105188
- 409 + 104779 = 105188
Showing the first eight; more decompositions exist.
