Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020018, here are decompositions:

5 + 1020013 = 1020018
7 + 1020011 = 1020018
11 + 1020007 = 1020018
17 + 1020001 = 1020018
47 + 1019971 = 1020018
157 + 1019861 = 1020018
179 + 1019839 = 1020018
191 + 1019827 = 1020018

Showing the first eight; more decompositions exist.
