Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520730, here are decompositions:

13 + 520717 = 520730
31 + 520699 = 520730
97 + 520633 = 520730
109 + 520621 = 520730
163 + 520567 = 520730
181 + 520549 = 520730
283 + 520447 = 520730
307 + 520423 = 520730

Showing the first eight; more decompositions exist.
