Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10806, here are decompositions:
- 7 + 10799 = 10806
- 17 + 10789 = 10806
- 53 + 10753 = 10806
- 67 + 10739 = 10806
- 73 + 10733 = 10806
- 83 + 10723 = 10806
- 97 + 10709 = 10806
- 139 + 10667 = 10806
Showing the first eight; more decompositions exist.
