Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170384, here are decompositions:
- 13 + 170371 = 170384
- 31 + 170353 = 170384
- 37 + 170347 = 170384
- 43 + 170341 = 170384
- 157 + 170227 = 170384
- 283 + 170101 = 170384
- 337 + 170047 = 170384
- 397 + 169987 = 170384
Showing the first eight; more decompositions exist.
