Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018374, here are decompositions:

17 + 1018357 = 1018374
37 + 1018337 = 1018374
61 + 1018313 = 1018374
73 + 1018301 = 1018374
83 + 1018291 = 1018374
103 + 1018271 = 1018374
127 + 1018247 = 1018374
151 + 1018223 = 1018374

Showing the first eight; more decompositions exist.
