Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022586, here are decompositions:

13 + 1022573 = 1022586
67 + 1022519 = 1022586
73 + 1022513 = 1022586
79 + 1022507 = 1022586
83 + 1022503 = 1022586
137 + 1022449 = 1022586
157 + 1022429 = 1022586
197 + 1022389 = 1022586

Showing the first eight; more decompositions exist.
