Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520524, here are decompositions:

73 + 520451 = 520524
97 + 520427 = 520524
101 + 520423 = 520524
113 + 520411 = 520524
131 + 520393 = 520524
163 + 520361 = 520524
167 + 520357 = 520524
211 + 520313 = 520524

Showing the first eight; more decompositions exist.
