Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80164, here are decompositions:
- 11 + 80153 = 80164
- 17 + 80147 = 80164
- 23 + 80141 = 80164
- 53 + 80111 = 80164
- 113 + 80051 = 80164
- 167 + 79997 = 80164
- 191 + 79973 = 80164
- 197 + 79967 = 80164
Showing the first eight; more decompositions exist.
