Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009404, here are decompositions:

5 + 1009399 = 1009404
17 + 1009387 = 1009404
31 + 1009373 = 1009404
43 + 1009361 = 1009404
47 + 1009357 = 1009404
61 + 1009343 = 1009404
83 + 1009321 = 1009404
101 + 1009303 = 1009404

Showing the first eight; more decompositions exist.
