Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66006, here are decompositions:
- 13 + 65993 = 66006
- 23 + 65983 = 66006
- 43 + 65963 = 66006
- 79 + 65927 = 66006
- 107 + 65899 = 66006
- 139 + 65867 = 66006
- 163 + 65843 = 66006
- 167 + 65839 = 66006
Showing the first eight; more decompositions exist.
