Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16524, here are decompositions:
- 5 + 16519 = 16524
- 31 + 16493 = 16524
- 37 + 16487 = 16524
- 43 + 16481 = 16524
- 47 + 16477 = 16524
- 71 + 16453 = 16524
- 73 + 16451 = 16524
- 97 + 16427 = 16524
Showing the first eight; more decompositions exist.
