Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189748, here are decompositions:
- 5 + 189743 = 189748
- 47 + 189701 = 189748
- 131 + 189617 = 189748
- 149 + 189599 = 189748
- 239 + 189509 = 189748
- 257 + 189491 = 189748
- 269 + 189479 = 189748
- 281 + 189467 = 189748
Showing the first eight; more decompositions exist.
