Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170690, here are decompositions:
- 43 + 170647 = 170690
- 139 + 170551 = 170690
- 151 + 170539 = 170690
- 181 + 170509 = 170690
- 193 + 170497 = 170690
- 277 + 170413 = 170690
- 307 + 170383 = 170690
- 337 + 170353 = 170690
Showing the first eight; more decompositions exist.
