Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665180, here are decompositions:

23 + 8665157 = 8665180
71 + 8665109 = 8665180
107 + 8665073 = 8665180
149 + 8665031 = 8665180
233 + 8664947 = 8665180
239 + 8664941 = 8665180
311 + 8664869 = 8665180
317 + 8664863 = 8665180

Showing the first eight; more decompositions exist.
