Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020146, here are decompositions:

3 + 1020143 = 1020146
37 + 1020109 = 1020146
67 + 1020079 = 1020146
97 + 1020049 = 1020146
103 + 1020043 = 1020146
109 + 1020037 = 1020146
139 + 1020007 = 1020146
307 + 1019839 = 1020146

Showing the first eight; more decompositions exist.
