Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169136, here are decompositions:
- 7 + 169129 = 169136
- 43 + 169093 = 169136
- 67 + 169069 = 169136
- 73 + 169063 = 169136
- 127 + 169009 = 169136
- 193 + 168943 = 169136
- 199 + 168937 = 169136
- 223 + 168913 = 169136
Showing the first eight; more decompositions exist.
