Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521606, here are decompositions:

3 + 521603 = 521606
67 + 521539 = 521606
73 + 521533 = 521606
79 + 521527 = 521606
103 + 521503 = 521606
109 + 521497 = 521606
229 + 521377 = 521606
277 + 521329 = 521606

Showing the first eight; more decompositions exist.
