Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020486, here are decompositions:

29 + 1020457 = 1020486
67 + 1020419 = 1020486
73 + 1020413 = 1020486
79 + 1020407 = 1020486
97 + 1020389 = 1020486
107 + 1020379 = 1020486
149 + 1020337 = 1020486
157 + 1020329 = 1020486

Showing the first eight; more decompositions exist.
