Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640574, here are decompositions:

71 + 8640503 = 8640574
167 + 8640407 = 8640574
311 + 8640263 = 8640574
353 + 8640221 = 8640574
557 + 8640017 = 8640574
587 + 8639987 = 8640574
653 + 8639921 = 8640574
821 + 8639753 = 8640574

Showing the first eight; more decompositions exist.
