Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640462, here are decompositions:

11 + 8640451 = 8640462
23 + 8640439 = 8640462
43 + 8640419 = 8640462
53 + 8640409 = 8640462
71 + 8640391 = 8640462
113 + 8640349 = 8640462
199 + 8640263 = 8640462
211 + 8640251 = 8640462

Showing the first eight; more decompositions exist.
