Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640474, here are decompositions:

23 + 8640451 = 8640474
47 + 8640427 = 8640474
67 + 8640407 = 8640474
83 + 8640391 = 8640474
137 + 8640337 = 8640474
211 + 8640263 = 8640474
223 + 8640251 = 8640474
233 + 8640241 = 8640474

Showing the first eight; more decompositions exist.
