Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020166, here are decompositions:

3 + 1020163 = 1020166
23 + 1020143 = 1020166
29 + 1020137 = 1020166
53 + 1020113 = 1020166
89 + 1020077 = 1020166
107 + 1020059 = 1020166
239 + 1019927 = 1020166
263 + 1019903 = 1020166

Showing the first eight; more decompositions exist.
