Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15852, here are decompositions:
- 29 + 15823 = 15852
- 43 + 15809 = 15852
- 61 + 15791 = 15852
- 79 + 15773 = 15852
- 103 + 15749 = 15852
- 113 + 15739 = 15852
- 173 + 15679 = 15852
- 181 + 15671 = 15852
Showing the first eight; more decompositions exist.
