Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018182, here are decompositions:

5 + 1018177 = 1018182
59 + 1018123 = 1018182
73 + 1018109 = 1018182
163 + 1018019 = 1018182
223 + 1017959 = 1018182
229 + 1017953 = 1018182
293 + 1017889 = 1018182
331 + 1017851 = 1018182

Showing the first eight; more decompositions exist.
