Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640504, here are decompositions:

11 + 8640493 = 8640504
23 + 8640481 = 8640504
53 + 8640451 = 8640504
97 + 8640407 = 8640504
113 + 8640391 = 8640504
167 + 8640337 = 8640504
241 + 8640263 = 8640504
263 + 8640241 = 8640504

Showing the first eight; more decompositions exist.
