Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018266, here are decompositions:

13 + 1018253 = 1018266
19 + 1018247 = 1018266
43 + 1018223 = 1018266
59 + 1018207 = 1018266
89 + 1018177 = 1018266
157 + 1018109 = 1018266
269 + 1017997 = 1018266
307 + 1017959 = 1018266

Showing the first eight; more decompositions exist.
