Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018216, here are decompositions:

107 + 1018109 = 1018216
197 + 1018019 = 1018216
257 + 1017959 = 1018216
263 + 1017953 = 1018216
293 + 1017923 = 1018216
359 + 1017857 = 1018216
389 + 1017827 = 1018216
467 + 1017749 = 1018216

Showing the first eight; more decompositions exist.
