Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669180, here are decompositions:

67 + 8669113 = 8669180
73 + 8669107 = 8669180
97 + 8669083 = 8669180
109 + 8669071 = 8669180
139 + 8669041 = 8669180
229 + 8668951 = 8669180
283 + 8668897 = 8669180
307 + 8668873 = 8669180

Showing the first eight; more decompositions exist.
