Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640616, here are decompositions:

29 + 8640587 = 8640616
113 + 8640503 = 8640616
197 + 8640419 = 8640616
353 + 8640263 = 8640616
419 + 8640197 = 8640616
557 + 8640059 = 8640616
599 + 8640017 = 8640616
797 + 8639819 = 8640616

Showing the first eight; more decompositions exist.
