Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66946, here are decompositions:
- 3 + 66943 = 66946
- 23 + 66923 = 66946
- 83 + 66863 = 66946
- 137 + 66809 = 66946
- 149 + 66797 = 66946
- 197 + 66749 = 66946
- 233 + 66713 = 66946
- 263 + 66683 = 66946
Showing the first eight; more decompositions exist.
