Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487522, here are decompositions:

41 + 487481 = 487522
53 + 487469 = 487522
59 + 487463 = 487522
131 + 487391 = 487522
173 + 487349 = 487522
239 + 487283 = 487522
311 + 487211 = 487522
389 + 487133 = 487522

Showing the first eight; more decompositions exist.
