Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520500, here are decompositions:

53 + 520447 = 520500
67 + 520433 = 520500
73 + 520427 = 520500
89 + 520411 = 520500
107 + 520393 = 520500
131 + 520369 = 520500
137 + 520363 = 520500
139 + 520361 = 520500

Showing the first eight; more decompositions exist.
