Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994388, here are decompositions:

19 + 994369 = 994388
67 + 994321 = 994388
79 + 994309 = 994388
139 + 994249 = 994388
151 + 994237 = 994388
337 + 994051 = 994388
349 + 994039 = 994388
547 + 993841 = 994388

Showing the first eight; more decompositions exist.
