Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997404, here are decompositions:

13 + 997391 = 997404
47 + 997357 = 997404
61 + 997343 = 997404
71 + 997333 = 997404
97 + 997307 = 997404
131 + 997273 = 997404
137 + 997267 = 997404
157 + 997247 = 997404

Showing the first eight; more decompositions exist.
