Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10840, here are decompositions:
- 3 + 10837 = 10840
- 41 + 10799 = 10840
- 59 + 10781 = 10840
- 101 + 10739 = 10840
- 107 + 10733 = 10840
- 131 + 10709 = 10840
- 149 + 10691 = 10840
- 173 + 10667 = 10840
Showing the first eight; more decompositions exist.
