Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16452, here are decompositions:
- 5 + 16447 = 16452
- 19 + 16433 = 16452
- 31 + 16421 = 16452
- 41 + 16411 = 16452
- 71 + 16381 = 16452
- 83 + 16369 = 16452
- 89 + 16363 = 16452
- 103 + 16349 = 16452
Showing the first eight; more decompositions exist.
