Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10878, here are decompositions:

11 + 10867 = 10878
17 + 10861 = 10878
19 + 10859 = 10878
31 + 10847 = 10878
41 + 10837 = 10878
47 + 10831 = 10878
79 + 10799 = 10878
89 + 10789 = 10878

Showing the first eight; more decompositions exist.
