Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16464, here are decompositions:
- 11 + 16453 = 16464
- 13 + 16451 = 16464
- 17 + 16447 = 16464
- 31 + 16433 = 16464
- 37 + 16427 = 16464
- 43 + 16421 = 16464
- 47 + 16417 = 16464
- 53 + 16411 = 16464
Showing the first eight; more decompositions exist.
