Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10786, here are decompositions:
- 5 + 10781 = 10786
- 47 + 10739 = 10786
- 53 + 10733 = 10786
- 173 + 10613 = 10786
- 179 + 10607 = 10786
- 197 + 10589 = 10786
- 227 + 10559 = 10786
- 257 + 10529 = 10786
Showing the first eight; more decompositions exist.
