Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665836, here are decompositions:

19 + 8665817 = 8665836
37 + 8665799 = 8665836
59 + 8665777 = 8665836
233 + 8665603 = 8665836
269 + 8665567 = 8665836
293 + 8665543 = 8665836
337 + 8665499 = 8665836
367 + 8665469 = 8665836

Showing the first eight; more decompositions exist.
