Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640926, here are decompositions:

37 + 8640889 = 8640926
43 + 8640883 = 8640926
67 + 8640859 = 8640926
103 + 8640823 = 8640926
109 + 8640817 = 8640926
127 + 8640799 = 8640926
139 + 8640787 = 8640926
193 + 8640733 = 8640926

Showing the first eight; more decompositions exist.
