Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19882, here are decompositions:
- 29 + 19853 = 19882
- 41 + 19841 = 19882
- 89 + 19793 = 19882
- 131 + 19751 = 19882
- 173 + 19709 = 19882
- 311 + 19571 = 19882
- 419 + 19463 = 19882
- 449 + 19433 = 19882
Showing the first eight; more decompositions exist.
