Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170188, here are decompositions:
- 47 + 170141 = 170188
- 89 + 170099 = 170188
- 107 + 170081 = 170188
- 131 + 170057 = 170188
- 167 + 170021 = 170188
- 197 + 169991 = 170188
- 251 + 169937 = 170188
- 269 + 169919 = 170188
Showing the first eight; more decompositions exist.
