Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66904, here are decompositions:
- 41 + 66863 = 66904
- 53 + 66851 = 66904
- 83 + 66821 = 66904
- 107 + 66797 = 66904
- 113 + 66791 = 66904
- 191 + 66713 = 66904
- 251 + 66653 = 66904
- 311 + 66593 = 66904
Showing the first eight; more decompositions exist.
