Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42164, here are decompositions:
- 7 + 42157 = 42164
- 103 + 42061 = 42164
- 151 + 42013 = 42164
- 181 + 41983 = 42164
- 211 + 41953 = 42164
- 223 + 41941 = 42164
- 271 + 41893 = 42164
- 277 + 41887 = 42164
Showing the first eight; more decompositions exist.
