Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640492, here are decompositions:

11 + 8640481 = 8640492
41 + 8640451 = 8640492
53 + 8640439 = 8640492
73 + 8640419 = 8640492
83 + 8640409 = 8640492
101 + 8640391 = 8640492
163 + 8640329 = 8640492
229 + 8640263 = 8640492

Showing the first eight; more decompositions exist.
