Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189370, here are decompositions:
- 17 + 189353 = 189370
- 23 + 189347 = 189370
- 59 + 189311 = 189370
- 113 + 189257 = 189370
- 131 + 189239 = 189370
- 353 + 189017 = 189370
- 359 + 189011 = 189370
- 431 + 188939 = 189370
Showing the first eight; more decompositions exist.
