Goldbach decomposition

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.
