Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019218, here are decompositions:

41 + 1019177 = 1019218
89 + 1019129 = 1019218
149 + 1019069 = 1019218
251 + 1018967 = 1019218
269 + 1018949 = 1019218
281 + 1018937 = 1019218
311 + 1018907 = 1019218
359 + 1018859 = 1019218

Showing the first eight; more decompositions exist.
