Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15876, here are decompositions:
- 17 + 15859 = 15876
- 53 + 15823 = 15876
- 59 + 15817 = 15876
- 67 + 15809 = 15876
- 73 + 15803 = 15876
- 79 + 15797 = 15876
- 89 + 15787 = 15876
- 103 + 15773 = 15876
Showing the first eight; more decompositions exist.
