Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189074, here are decompositions:
- 7 + 189067 = 189074
- 13 + 189061 = 189074
- 31 + 189043 = 189074
- 163 + 188911 = 189074
- 211 + 188863 = 189074
- 241 + 188833 = 189074
- 283 + 188791 = 189074
- 307 + 188767 = 189074
Showing the first eight; more decompositions exist.
