Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028486, here are decompositions:

7 + 1028479 = 1028486
13 + 1028473 = 1028486
97 + 1028389 = 1028486
157 + 1028329 = 1028486
223 + 1028263 = 1028486
337 + 1028149 = 1028486
373 + 1028113 = 1028486
379 + 1028107 = 1028486

Showing the first eight; more decompositions exist.
