Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66982, here are decompositions:
- 5 + 66977 = 66982
- 23 + 66959 = 66982
- 59 + 66923 = 66982
- 131 + 66851 = 66982
- 173 + 66809 = 66982
- 191 + 66791 = 66982
- 233 + 66749 = 66982
- 269 + 66713 = 66982
Showing the first eight; more decompositions exist.
