Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012212, here are decompositions:

11 + 1012201 = 1012212
23 + 1012189 = 1012212
29 + 1012183 = 1012212
41 + 1012171 = 1012212
53 + 1012159 = 1012212
79 + 1012133 = 1012212
109 + 1012103 = 1012212
163 + 1012049 = 1012212

Showing the first eight; more decompositions exist.
