Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66164, here are decompositions:
- 3 + 66161 = 66164
- 61 + 66103 = 66164
- 97 + 66067 = 66164
- 127 + 66037 = 66164
- 181 + 65983 = 66164
- 283 + 65881 = 66164
- 313 + 65851 = 66164
- 337 + 65827 = 66164
Showing the first eight; more decompositions exist.
