Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030420, here are decompositions:

3 + 1030417 = 1030420
59 + 1030361 = 1030420
71 + 1030349 = 1030420
113 + 1030307 = 1030420
173 + 1030247 = 1030420
179 + 1030241 = 1030420
239 + 1030181 = 1030420
263 + 1030157 = 1030420

Showing the first eight; more decompositions exist.
