Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505530, here are decompositions:

7 + 505523 = 505530
17 + 505513 = 505530
19 + 505511 = 505530
29 + 505501 = 505530
37 + 505493 = 505530
61 + 505469 = 505530
71 + 505459 = 505530
83 + 505447 = 505530

Showing the first eight; more decompositions exist.
