Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045404, here are decompositions:

7 + 1045397 = 1045404
11 + 1045393 = 1045404
13 + 1045391 = 1045404
37 + 1045367 = 1045404
83 + 1045321 = 1045404
97 + 1045307 = 1045404
127 + 1045277 = 1045404
131 + 1045273 = 1045404

Showing the first eight; more decompositions exist.
