Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520486, here are decompositions:

53 + 520433 = 520486
59 + 520427 = 520486
107 + 520379 = 520486
137 + 520349 = 520486
173 + 520313 = 520486
179 + 520307 = 520486
293 + 520193 = 520486
383 + 520103 = 520486

Showing the first eight; more decompositions exist.
