Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640532, here are decompositions:

29 + 8640503 = 8640532
113 + 8640419 = 8640532
269 + 8640263 = 8640532
281 + 8640251 = 8640532
311 + 8640221 = 8640532
683 + 8639849 = 8640532
821 + 8639711 = 8640532
941 + 8639591 = 8640532

Showing the first eight; more decompositions exist.
