Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666636, here are decompositions:

103 + 8666533 = 8666636
157 + 8666479 = 8666636
193 + 8666443 = 8666636
313 + 8666323 = 8666636
367 + 8666269 = 8666636
463 + 8666173 = 8666636
499 + 8666137 = 8666636
577 + 8666059 = 8666636

Showing the first eight; more decompositions exist.
