Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653872, here are decompositions:

13 + 8653859 = 8653872
61 + 8653811 = 8653872
83 + 8653789 = 8653872
103 + 8653769 = 8653872
109 + 8653763 = 8653872
131 + 8653741 = 8653872
163 + 8653709 = 8653872
173 + 8653699 = 8653872

Showing the first eight; more decompositions exist.
