Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717892, here are decompositions:

11 + 8717881 = 8717892
19 + 8717873 = 8717892
23 + 8717869 = 8717892
31 + 8717861 = 8717892
83 + 8717809 = 8717892
89 + 8717803 = 8717892
101 + 8717791 = 8717892
109 + 8717783 = 8717892

Showing the first eight; more decompositions exist.
