Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42160, here are decompositions:
- 3 + 42157 = 42160
- 29 + 42131 = 42160
- 59 + 42101 = 42160
- 71 + 42089 = 42160
- 89 + 42071 = 42160
- 137 + 42023 = 42160
- 179 + 41981 = 42160
- 191 + 41969 = 42160
Showing the first eight; more decompositions exist.
