Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018304, here are decompositions:

3 + 1018301 = 1018304
13 + 1018291 = 1018304
97 + 1018207 = 1018304
103 + 1018201 = 1018304
127 + 1018177 = 1018304
181 + 1018123 = 1018304
283 + 1018021 = 1018304
307 + 1017997 = 1018304

Showing the first eight; more decompositions exist.
