Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718892, here are decompositions:

5 + 8718887 = 8718892
11 + 8718881 = 8718892
23 + 8718869 = 8718892
41 + 8718851 = 8718892
53 + 8718839 = 8718892
59 + 8718833 = 8718892
89 + 8718803 = 8718892
113 + 8718779 = 8718892

Showing the first eight; more decompositions exist.
