Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683878, here are decompositions:

97 + 8683781 = 8683878
109 + 8683769 = 8683878
149 + 8683729 = 8683878
179 + 8683699 = 8683878
191 + 8683687 = 8683878
197 + 8683681 = 8683878
239 + 8683639 = 8683878
241 + 8683637 = 8683878

Showing the first eight; more decompositions exist.
