Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15846, here are decompositions:
- 23 + 15823 = 15846
- 29 + 15817 = 15846
- 37 + 15809 = 15846
- 43 + 15803 = 15846
- 59 + 15787 = 15846
- 73 + 15773 = 15846
- 79 + 15767 = 15846
- 97 + 15749 = 15846
Showing the first eight; more decompositions exist.
