Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019404, here are decompositions:

5 + 1019399 = 1019404
47 + 1019357 = 1019404
53 + 1019351 = 1019404
107 + 1019297 = 1019404
131 + 1019273 = 1019404
137 + 1019267 = 1019404
167 + 1019237 = 1019404
227 + 1019177 = 1019404

Showing the first eight; more decompositions exist.
