Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653864, here are decompositions:

5 + 8653859 = 8653864
17 + 8653847 = 8653864
47 + 8653817 = 8653864
53 + 8653811 = 8653864
101 + 8653763 = 8653864
173 + 8653691 = 8653864
251 + 8653613 = 8653864
311 + 8653553 = 8653864

Showing the first eight; more decompositions exist.
