Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520808, here are decompositions:

61 + 520747 = 520808
109 + 520699 = 520808
199 + 520609 = 520808
241 + 520567 = 520808
397 + 520411 = 520808
439 + 520369 = 520808
499 + 520309 = 520808
787 + 520021 = 520808

Showing the first eight; more decompositions exist.
