Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15932, here are decompositions:
- 13 + 15919 = 15932
- 19 + 15913 = 15932
- 31 + 15901 = 15932
- 43 + 15889 = 15932
- 73 + 15859 = 15932
- 109 + 15823 = 15932
- 193 + 15739 = 15932
- 199 + 15733 = 15932
Showing the first eight; more decompositions exist.
