Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10894, here are decompositions:

3 + 10891 = 10894
5 + 10889 = 10894
11 + 10883 = 10894
41 + 10853 = 10894
47 + 10847 = 10894
113 + 10781 = 10894
227 + 10667 = 10894
263 + 10631 = 10894

Showing the first eight; more decompositions exist.
