Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640404, here are decompositions:

13 + 8640391 = 8640404
67 + 8640337 = 8640404
163 + 8640241 = 8640404
193 + 8640211 = 8640404
271 + 8640133 = 8640404
541 + 8639863 = 8640404
601 + 8639803 = 8640404
607 + 8639797 = 8640404

Showing the first eight; more decompositions exist.
