Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640526, here are decompositions:

23 + 8640503 = 8640526
107 + 8640419 = 8640526
197 + 8640329 = 8640526
239 + 8640287 = 8640526
263 + 8640263 = 8640526
467 + 8640059 = 8640526
509 + 8640017 = 8640526
617 + 8639909 = 8640526

Showing the first eight; more decompositions exist.
