Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520658, here are decompositions:

37 + 520621 = 520658
109 + 520549 = 520658
211 + 520447 = 520658
277 + 520381 = 520658
349 + 520309 = 520658
367 + 520291 = 520658
379 + 520279 = 520658
547 + 520111 = 520658

Showing the first eight; more decompositions exist.
