Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665554, here are decompositions:

11 + 8665543 = 8665554
13 + 8665541 = 8665554
83 + 8665471 = 8665554
103 + 8665451 = 8665554
113 + 8665441 = 8665554
181 + 8665373 = 8665554
193 + 8665361 = 8665554
197 + 8665357 = 8665554

Showing the first eight; more decompositions exist.
