Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16504, here are decompositions:
- 11 + 16493 = 16504
- 17 + 16487 = 16504
- 23 + 16481 = 16504
- 53 + 16451 = 16504
- 71 + 16433 = 16504
- 83 + 16421 = 16504
- 251 + 16253 = 16504
- 281 + 16223 = 16504
Showing the first eight; more decompositions exist.
