Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022588, here are decompositions:

79 + 1022509 = 1022588
97 + 1022491 = 1022588
139 + 1022449 = 1022588
199 + 1022389 = 1022588
211 + 1022377 = 1022588
337 + 1022251 = 1022588
379 + 1022209 = 1022588
397 + 1022191 = 1022588

Showing the first eight; more decompositions exist.
