Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018356, here are decompositions:

19 + 1018337 = 1018356
43 + 1018313 = 1018356
47 + 1018309 = 1018356
103 + 1018253 = 1018356
109 + 1018247 = 1018356
139 + 1018217 = 1018356
149 + 1018207 = 1018356
179 + 1018177 = 1018356

Showing the first eight; more decompositions exist.
