Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666120, here are decompositions:

61 + 8666059 = 8666120
97 + 8666023 = 8666120
103 + 8666017 = 8666120
181 + 8665939 = 8666120
223 + 8665897 = 8666120
271 + 8665849 = 8666120
487 + 8665633 = 8666120
577 + 8665543 = 8666120

Showing the first eight; more decompositions exist.
