Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189424, here are decompositions:
- 3 + 189421 = 189424
- 17 + 189407 = 189424
- 23 + 189401 = 189424
- 47 + 189377 = 189424
- 71 + 189353 = 189424
- 113 + 189311 = 189424
- 167 + 189257 = 189424
- 173 + 189251 = 189424
Showing the first eight; more decompositions exist.
