Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64464, here are decompositions:
- 11 + 64453 = 64464
- 13 + 64451 = 64464
- 31 + 64433 = 64464
- 61 + 64403 = 64464
- 83 + 64381 = 64464
- 131 + 64333 = 64464
- 137 + 64327 = 64464
- 163 + 64301 = 64464
Showing the first eight; more decompositions exist.
