Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66964, here are decompositions:
- 5 + 66959 = 66964
- 17 + 66947 = 66964
- 41 + 66923 = 66964
- 101 + 66863 = 66964
- 113 + 66851 = 66964
- 167 + 66797 = 66964
- 173 + 66791 = 66964
- 251 + 66713 = 66964
Showing the first eight; more decompositions exist.
