Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64120, here are decompositions:
- 11 + 64109 = 64120
- 29 + 64091 = 64120
- 53 + 64067 = 64120
- 83 + 64037 = 64120
- 101 + 64019 = 64120
- 107 + 64013 = 64120
- 113 + 64007 = 64120
- 191 + 63929 = 64120
Showing the first eight; more decompositions exist.
