Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022386, here are decompositions:

3 + 1022383 = 1022386
5 + 1022381 = 1022386
83 + 1022303 = 1022386
137 + 1022249 = 1022386
149 + 1022237 = 1022386
257 + 1022129 = 1022386
263 + 1022123 = 1022386
353 + 1022033 = 1022386

Showing the first eight; more decompositions exist.
