Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10864, here are decompositions:

3 + 10861 = 10864
5 + 10859 = 10864
11 + 10853 = 10864
17 + 10847 = 10864
83 + 10781 = 10864
131 + 10733 = 10864
173 + 10691 = 10864
197 + 10667 = 10864

Showing the first eight; more decompositions exist.
