Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994138, here are decompositions:

71 + 994067 = 994138
251 + 993887 = 994138
269 + 993869 = 994138
311 + 993827 = 994138
317 + 993821 = 994138
359 + 993779 = 994138
449 + 993689 = 994138
491 + 993647 = 994138

Showing the first eight; more decompositions exist.
