Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68164, here are decompositions:
- 3 + 68161 = 68164
- 17 + 68147 = 68164
- 23 + 68141 = 68164
- 53 + 68111 = 68164
- 197 + 67967 = 68164
- 233 + 67931 = 68164
- 263 + 67901 = 68164
- 281 + 67883 = 68164
Showing the first eight; more decompositions exist.
