Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510520, here are decompositions:

71 + 510449 = 510520
137 + 510383 = 510520
233 + 510287 = 510520
293 + 510227 = 510520
317 + 510203 = 510520
383 + 510137 = 510520
419 + 510101 = 510520
431 + 510089 = 510520

Showing the first eight; more decompositions exist.
