Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639892, here are decompositions:

29 + 8639863 = 8639892
43 + 8639849 = 8639892
73 + 8639819 = 8639892
83 + 8639809 = 8639892
89 + 8639803 = 8639892
113 + 8639779 = 8639892
139 + 8639753 = 8639892
179 + 8639713 = 8639892

Showing the first eight; more decompositions exist.
