Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640936, here are decompositions:

47 + 8640889 = 8640936
53 + 8640883 = 8640936
113 + 8640823 = 8640936
137 + 8640799 = 8640936
149 + 8640787 = 8640936
197 + 8640739 = 8640936
223 + 8640713 = 8640936
229 + 8640707 = 8640936

Showing the first eight; more decompositions exist.
