Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030388, here are decompositions:

19 + 1030369 = 1030388
31 + 1030357 = 1030388
97 + 1030291 = 1030388
277 + 1030111 = 1030388
349 + 1030039 = 1030388
367 + 1030021 = 1030388
421 + 1029967 = 1030388
547 + 1029841 = 1030388

Showing the first eight; more decompositions exist.
