Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018212, here are decompositions:

5 + 1018207 = 1018212
11 + 1018201 = 1018212
89 + 1018123 = 1018212
103 + 1018109 = 1018212
191 + 1018021 = 1018212
193 + 1018019 = 1018212
331 + 1017881 = 1018212
353 + 1017859 = 1018212

Showing the first eight; more decompositions exist.
