Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40006, here are decompositions:
- 17 + 39989 = 40006
- 23 + 39983 = 40006
- 53 + 39953 = 40006
- 137 + 39869 = 40006
- 149 + 39857 = 40006
- 167 + 39839 = 40006
- 179 + 39827 = 40006
- 227 + 39779 = 40006
Showing the first eight; more decompositions exist.
