Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022388, here are decompositions:

5 + 1022383 = 1022388
7 + 1022381 = 1022388
11 + 1022377 = 1022388
47 + 1022341 = 1022388
97 + 1022291 = 1022388
137 + 1022251 = 1022388
139 + 1022249 = 1022388
151 + 1022237 = 1022388

Showing the first eight; more decompositions exist.
