Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523404, here are decompositions:

17 + 523387 = 523404
47 + 523357 = 523404
53 + 523351 = 523404
71 + 523333 = 523404
97 + 523307 = 523404
107 + 523297 = 523404
191 + 523213 = 523404
197 + 523207 = 523404

Showing the first eight; more decompositions exist.
