Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10906, here are decompositions:
- 3 + 10903 = 10906
- 17 + 10889 = 10906
- 23 + 10883 = 10906
- 47 + 10859 = 10906
- 53 + 10853 = 10906
- 59 + 10847 = 10906
- 107 + 10799 = 10906
- 167 + 10739 = 10906
Showing the first eight; more decompositions exist.
