Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169936, here are decompositions:
- 3 + 169933 = 169936
- 17 + 169919 = 169936
- 23 + 169913 = 169936
- 47 + 169889 = 169936
- 113 + 169823 = 169936
- 167 + 169769 = 169936
- 227 + 169709 = 169936
- 269 + 169667 = 169936
Showing the first eight; more decompositions exist.
