Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19852, here are decompositions:
- 11 + 19841 = 19852
- 59 + 19793 = 19852
- 89 + 19763 = 19852
- 101 + 19751 = 19852
- 113 + 19739 = 19852
- 191 + 19661 = 19852
- 269 + 19583 = 19852
- 281 + 19571 = 19852
Showing the first eight; more decompositions exist.
