Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016180, here are decompositions:

7 + 1016173 = 1016180
37 + 1016143 = 1016180
43 + 1016137 = 1016180
97 + 1016083 = 1016180
127 + 1016053 = 1016180
157 + 1016023 = 1016180
199 + 1015981 = 1016180
283 + 1015897 = 1016180

Showing the first eight; more decompositions exist.
