Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018350, here are decompositions:

13 + 1018337 = 1018350
37 + 1018313 = 1018350
41 + 1018309 = 1018350
59 + 1018291 = 1018350
79 + 1018271 = 1018350
97 + 1018253 = 1018350
103 + 1018247 = 1018350
127 + 1018223 = 1018350

Showing the first eight; more decompositions exist.
