Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42108, here are decompositions:
- 7 + 42101 = 42108
- 19 + 42089 = 42108
- 37 + 42071 = 42108
- 47 + 42061 = 42108
- 89 + 42019 = 42108
- 109 + 41999 = 42108
- 127 + 41981 = 42108
- 139 + 41969 = 42108
Showing the first eight; more decompositions exist.
