Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64066, here are decompositions:
- 3 + 64063 = 64066
- 29 + 64037 = 64066
- 47 + 64019 = 64066
- 53 + 64013 = 64066
- 59 + 64007 = 64066
- 89 + 63977 = 64066
- 137 + 63929 = 64066
- 227 + 63839 = 64066
Showing the first eight; more decompositions exist.
