Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57664, here are decompositions:
- 11 + 57653 = 57664
- 23 + 57641 = 57664
- 71 + 57593 = 57664
- 107 + 57557 = 57664
- 137 + 57527 = 57664
- 197 + 57467 = 57664
- 251 + 57413 = 57664
- 281 + 57383 = 57664
Showing the first eight; more decompositions exist.
