Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640794, here are decompositions:

7 + 8640787 = 8640794
13 + 8640781 = 8640794
61 + 8640733 = 8640794
103 + 8640691 = 8640794
193 + 8640601 = 8640794
241 + 8640553 = 8640794
313 + 8640481 = 8640794
367 + 8640427 = 8640794

Showing the first eight; more decompositions exist.
