Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020406, here are decompositions:

5 + 1020401 = 1020406
17 + 1020389 = 1020406
53 + 1020353 = 1020406
113 + 1020293 = 1020406
137 + 1020269 = 1020406
173 + 1020233 = 1020406
263 + 1020143 = 1020406
269 + 1020137 = 1020406

Showing the first eight; more decompositions exist.
