Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640576, here are decompositions:

17 + 8640559 = 8640576
23 + 8640553 = 8640576
29 + 8640547 = 8640576
73 + 8640503 = 8640576
83 + 8640493 = 8640576
137 + 8640439 = 8640576
149 + 8640427 = 8640576
157 + 8640419 = 8640576

Showing the first eight; more decompositions exist.
