Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635920, here are decompositions:

23 + 8635897 = 8635920
37 + 8635883 = 8635920
53 + 8635867 = 8635920
67 + 8635853 = 8635920
71 + 8635849 = 8635920
103 + 8635817 = 8635920
109 + 8635811 = 8635920
191 + 8635729 = 8635920

Showing the first eight; more decompositions exist.
