Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759666, here are decompositions:

109 + 8759557 = 8759666
163 + 8759503 = 8759666
199 + 8759467 = 8759666
313 + 8759353 = 8759666
367 + 8759299 = 8759666
379 + 8759287 = 8759666
499 + 8759167 = 8759666
577 + 8759089 = 8759666

Showing the first eight; more decompositions exist.
