Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020286, here are decompositions:

17 + 1020269 = 1020286
53 + 1020233 = 1020286
149 + 1020137 = 1020286
173 + 1020113 = 1020286
227 + 1020059 = 1020286
263 + 1020023 = 1020286
359 + 1019927 = 1020286
383 + 1019903 = 1020286

Showing the first eight; more decompositions exist.
