Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189504, here are decompositions:
- 11 + 189493 = 189504
- 13 + 189491 = 189504
- 31 + 189473 = 189504
- 37 + 189467 = 189504
- 41 + 189463 = 189504
- 67 + 189437 = 189504
- 71 + 189433 = 189504
- 83 + 189421 = 189504
Showing the first eight; more decompositions exist.
