Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665766, here are decompositions:

163 + 8665603 = 8665766
199 + 8665567 = 8665766
223 + 8665543 = 8665766
337 + 8665429 = 8665766
397 + 8665369 = 8665766
409 + 8665357 = 8665766
433 + 8665333 = 8665766
463 + 8665303 = 8665766

Showing the first eight; more decompositions exist.
