Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66994, here are decompositions:
- 17 + 66977 = 66994
- 47 + 66947 = 66994
- 71 + 66923 = 66994
- 131 + 66863 = 66994
- 173 + 66821 = 66994
- 197 + 66797 = 66994
- 281 + 66713 = 66994
- 293 + 66701 = 66994
Showing the first eight; more decompositions exist.
