Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018306, here are decompositions:

5 + 1018301 = 1018306
53 + 1018253 = 1018306
59 + 1018247 = 1018306
83 + 1018223 = 1018306
89 + 1018217 = 1018306
197 + 1018109 = 1018306
347 + 1017959 = 1018306
353 + 1017953 = 1018306

Showing the first eight; more decompositions exist.
