Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189984, here are decompositions:
- 7 + 189977 = 189984
- 17 + 189967 = 189984
- 23 + 189961 = 189984
- 37 + 189947 = 189984
- 71 + 189913 = 189984
- 83 + 189901 = 189984
- 97 + 189887 = 189984
- 103 + 189881 = 189984
Showing the first eight; more decompositions exist.
