Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64080, here are decompositions:
- 13 + 64067 = 64080
- 17 + 64063 = 64080
- 43 + 64037 = 64080
- 47 + 64033 = 64080
- 61 + 64019 = 64080
- 67 + 64013 = 64080
- 73 + 64007 = 64080
- 83 + 63997 = 64080
Showing the first eight; more decompositions exist.
