Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022542, here are decompositions:

11 + 1022531 = 1022542
23 + 1022519 = 1022542
29 + 1022513 = 1022542
41 + 1022501 = 1022542
113 + 1022429 = 1022542
239 + 1022303 = 1022542
251 + 1022291 = 1022542
293 + 1022249 = 1022542

Showing the first eight; more decompositions exist.
