Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15826, here are decompositions:
- 3 + 15823 = 15826
- 17 + 15809 = 15826
- 23 + 15803 = 15826
- 29 + 15797 = 15826
- 53 + 15773 = 15826
- 59 + 15767 = 15826
- 89 + 15737 = 15826
- 179 + 15647 = 15826
Showing the first eight; more decompositions exist.
