Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020456, here are decompositions:

5 + 1020451 = 1020456
37 + 1020419 = 1020456
43 + 1020413 = 1020456
67 + 1020389 = 1020456
103 + 1020353 = 1020456
127 + 1020329 = 1020456
163 + 1020293 = 1020456
197 + 1020259 = 1020456

Showing the first eight; more decompositions exist.
