Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10892, here are decompositions:

3 + 10889 = 10892
31 + 10861 = 10892
61 + 10831 = 10892
103 + 10789 = 10892
139 + 10753 = 10892
163 + 10729 = 10892
181 + 10711 = 10892
229 + 10663 = 10892

Showing the first eight; more decompositions exist.
