Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10900, here are decompositions:
- 11 + 10889 = 10900
- 17 + 10883 = 10900
- 41 + 10859 = 10900
- 47 + 10853 = 10900
- 53 + 10847 = 10900
- 101 + 10799 = 10900
- 167 + 10733 = 10900
- 191 + 10709 = 10900
Showing the first eight; more decompositions exist.
