Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189340, here are decompositions:
- 3 + 189337 = 189340
- 29 + 189311 = 189340
- 83 + 189257 = 189340
- 89 + 189251 = 189340
- 101 + 189239 = 189340
- 191 + 189149 = 189340
- 383 + 188957 = 189340
- 401 + 188939 = 189340
Showing the first eight; more decompositions exist.
