Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16164, here are decompositions:
- 23 + 16141 = 16164
- 37 + 16127 = 16164
- 53 + 16111 = 16164
- 61 + 16103 = 16164
- 67 + 16097 = 16164
- 73 + 16091 = 16164
- 97 + 16067 = 16164
- 101 + 16063 = 16164
Showing the first eight; more decompositions exist.
