Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658180, here are decompositions:

19 + 8658161 = 8658180
43 + 8658137 = 8658180
71 + 8658109 = 8658180
73 + 8658107 = 8658180
79 + 8658101 = 8658180
137 + 8658043 = 8658180
163 + 8658017 = 8658180
197 + 8657983 = 8658180

Showing the first eight; more decompositions exist.
