Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006218, here are decompositions:

29 + 1006189 = 1006218
41 + 1006177 = 1006218
47 + 1006171 = 1006218
67 + 1006151 = 1006218
71 + 1006147 = 1006218
127 + 1006091 = 1006218
131 + 1006087 = 1006218
181 + 1006037 = 1006218

Showing the first eight; more decompositions exist.
