Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105172, here are decompositions:
- 5 + 105167 = 105172
- 29 + 105143 = 105172
- 101 + 105071 = 105172
- 149 + 105023 = 105172
- 173 + 104999 = 105172
- 239 + 104933 = 105172
- 281 + 104891 = 105172
- 293 + 104879 = 105172
Showing the first eight; more decompositions exist.
