Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665040, here are decompositions:

19 + 8665021 = 8665040
61 + 8664979 = 8665040
79 + 8664961 = 8665040
193 + 8664847 = 8665040
283 + 8664757 = 8665040
379 + 8664661 = 8665040
487 + 8664553 = 8665040
523 + 8664517 = 8665040

Showing the first eight; more decompositions exist.
