Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989404, here are decompositions:

23 + 989381 = 989404
83 + 989321 = 989404
173 + 989231 = 989404
233 + 989171 = 989404
281 + 989123 = 989404
467 + 988937 = 989404
503 + 988901 = 989404
641 + 988763 = 989404

Showing the first eight; more decompositions exist.
