Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653908, here are decompositions:

5 + 8653903 = 8653908
17 + 8653891 = 8653908
19 + 8653889 = 8653908
31 + 8653877 = 8653908
61 + 8653847 = 8653908
97 + 8653811 = 8653908
101 + 8653807 = 8653908
139 + 8653769 = 8653908

Showing the first eight; more decompositions exist.
