Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189704, here are decompositions:
- 3 + 189701 = 189704
- 7 + 189697 = 189704
- 13 + 189691 = 189704
- 43 + 189661 = 189704
- 61 + 189643 = 189704
- 157 + 189547 = 189704
- 181 + 189523 = 189704
- 211 + 189493 = 189704
Showing the first eight; more decompositions exist.
