Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012218, here are decompositions:

5 + 1012213 = 1012218
17 + 1012201 = 1012218
29 + 1012189 = 1012218
47 + 1012171 = 1012218
59 + 1012159 = 1012218
71 + 1012147 = 1012218
131 + 1012087 = 1012218
139 + 1012079 = 1012218

Showing the first eight; more decompositions exist.
