Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66970, here are decompositions:
- 11 + 66959 = 66970
- 23 + 66947 = 66970
- 47 + 66923 = 66970
- 107 + 66863 = 66970
- 149 + 66821 = 66970
- 173 + 66797 = 66970
- 179 + 66791 = 66970
- 257 + 66713 = 66970
Showing the first eight; more decompositions exist.
