Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025404, here are decompositions:

11 + 1025393 = 1025404
53 + 1025351 = 1025404
71 + 1025333 = 1025404
101 + 1025303 = 1025404
131 + 1025273 = 1025404
137 + 1025267 = 1025404
173 + 1025231 = 1025404
251 + 1025153 = 1025404

Showing the first eight; more decompositions exist.
